Soma (Chandra)

Chandra derives from the Sanskrit root chand — to shine, to be bright — meaning simply the brilliant one. Soma, one of his oldest and most theologically layered names, belongs first to the sacred plant whose pressed juice was the supreme oblation of Vedic sacrifice, believed to nourish the gods and confer immortality; the identification of the moon itself with Soma — as the vessel storing that substance, drained by the gods each fortnight as it wanes — is a central concept of Vedic cosmology. Indu names the bright drop of soma juice specifically. Sasanka — "he who bears the mark of the hare" — and Mriganka — "marked with the deer" — read the moon's dark surface markings two different ways. Nishanatha means lord of the night; Oshadhipati, lord of herbs and medicinal plants; Nakshatranatha, lord of the nakshatras. Himamshu — "he whose rays are cool" — contrasts him directly with the sun's heat. Atrisuta simply means son of Atri.

In the dominant Puranic account, his father is Atri, one of the seven primordial sages and a mind-born son of Brahma, and his mother is Anusuya — celebrated across the tradition as the paradigm of wifely devotion, the sage whose fidelity was tested when the wives of the Trimurti sent their husbands to her hermitage in disguise, and who met the test by transforming Brahma, Vishnu, and Shiva into infants and nursing them. Anusuya bore Atri three divine sons: Chandra, the irascible sage Durvasa, and Dattatreya, the composite avatar of the Trimurti.

Chandra's twenty-seven wives are the daughters of Daksha, each identified with one of the twenty-seven nakshatras of the lunar calendar — Ashvini, Bharani, Krittika, Rohini, and so on through Revati. Of these, Rohini — the fourth nakshatra, identified with the bright red star Aldebaran — was by far his favorite, and his neglect of the other twenty-six in her favor sets the entire narrative below in motion. His principal son is Budha, born of a union that is itself one of the tradition's most consequential episodes. Chandra is also, by one textual strand, the father of Varchas, a being of pure brilliance who later incarnates as Abhimanyu, Arjuna's son — making Chandra the divine grandfather of Abhimanyu and the great-divine-grandfather of Parikshit, whose story frames the Bhagavata Purana's own recitation.

The identity of Chandra and Soma is fundamental to his religious significance and predates the Puranic genealogical tradition by many centuries. The Rigveda's ninth Mandala is devoted entirely to hymns praising Soma as the sacrificial drink, with the identification of that Soma with the moon already present in germ. The moon as a distinct deity is named explicitly in the Purusha Sukta, where he is said to be born from the mind of the cosmic Purusha at the first sacrifice — a cosmogonic account establishing the moon's enduring association with mind and mental fluctuation, a connection the later philosophical tradition elaborates at length. The Shatapatha Brahmana develops the theology further: the moon wanes each fortnight because the gods drink the soma stored within it, and waxes again as the soma is replenished — the cosmological foundation on which the Puranic narrative of Daksha's curse, below, is built.

The Bhagavata and Vishnu Puranas narrate Chandra's birth as the fruit of Atri's extraordinary austerity. Meditating on Mount Rishyamuka with his mind and vital breath concentrated in his eyes, held fixed for an immense span of time, Atri accumulated spiritual energy so intense that it overflowed as a flood of light pouring through all ten directions of space. The ten directional goddesses attempted to bear this light but found it too powerful for any one of them to hold, and it fell to earth as the embryo of the moon. Brahma, recognizing what had been produced, took the luminous form and set it in the sky, appointing Chandra lord of the nakshatras, lord of plant life, and the vessel of the soma drunk by gods and ancestors alike.

Daksha gave his twenty-seven daughters to Chandra on the explicit condition that he treat each with equal affection. Chandra instead lavished his attention almost entirely on Rohini, neglecting the rest so completely that they went to their father in grief. Daksha summoned Chandra and warned him — repeatedly, the texts stress — to honor all his wives equally. Chandra ignored every warning and continued exactly as before.

His patience exhausted, Daksha pronounced a formal curse: Chandra would suffer kshaya, a progressive wasting, causing him to diminish without ceasing. The consequences rippled through the entire cosmos at once. As Chandra wasted, the soma stored within him dwindled, and the gods who depended on it grew alarmed. Plant life, which drew its vitality from his rays, began to wither. The ancestors, sustained by lunar soma offered in ritual, suffered distress of their own. The gods appealed to Brahma, who sent Chandra to the sacred tirtha at Prabhasa to bathe and worship Shiva with total devotion. Chandra obeyed, and Shiva, pleased, agreed to soften the curse — though a curse properly pronounced could not be undone outright, only moderated. The compromise became the lunar month itself: Chandra wanes for fifteen days as the gods and ancestors draw their soma, then waxes for fifteen more as it is replenished — an unending cycle the tradition offers as its direct mythological account of why the moon has phases at all.

The second defining episode of Chandra's biography concerns Tara, wife of Brihaspati, the divine preceptor of the gods. Overcome with desire, Chandra abducted her and refused every demand from Brihaspati and the gods to return her. The conflict escalated into open war — the Tarakamaya, the war of Tara — with certain demons siding with Chandra against the gods, who stood behind their preceptor's claim. Only when Brahma intervened directly, commanding Chandra to return her and declaring the abduction a disgrace, did Chandra relent.

Tara returned to Brihaspati pregnant, and the paternity of the child became a matter of grave concern among the assembled gods. Questioned repeatedly, Tara was silent at first from shame, until Brahma pressed her to speak the truth — and she admitted the child was Chandra's. That child was Budha, a being of extraordinary brilliance and learning, identified with the planet Mercury. The Puranas do not soften the moral weight of how he came to be: both the Bhagavata and Vishnu Puranas present the abduction as a genuine transgression, a violation of a teacher's household driven by uncontrolled desire, and the tradition does not exonerate Chandra for it. And yet Budha himself is treated as one of the great planetary deities, and it is through him — origin notwithstanding — that the entire Chandravamsha, the dynasty of the Mahabharata's heroes, descends.

Chandra's sovereignty over the plant world runs consistently from the Rigveda through the Puranas: the moon's light and the soma it embodies are understood as the source of the vital moisture on which all plant life depends, waning with him as he wastes and reviving as he waxes — the same substance nourishing the gods in sacrifice and the fields in the ordinary world at once. His crescent form is also inseparable from Shiva's iconography: when Shiva intervened to soften Daksha's curse, he took the partially restored crescent and set it in his own matted hair, where it remains as a permanent emblem of that act of grace — a detail that makes Chandra's biography part of Shiva's own visual identity across the tradition.

In the Jyotisha tradition, Chandra is one of the nine Navagrahas — the planetary deities whose positions govern human destiny — and is considered the graha of mind, emotion, and mental disposition, a role tracing directly back to the Purusha Sukta's identification of the moon with the mind of the cosmic person. He is exalted in the nakshatra of Rohini, his most beloved wife — the mythological narrative confirmed, in a sense, at the level of astrological doctrine — and debilitated in Vrishchika, directly opposite. His associations include the pearl, silver, Monday (Somavar, Soma's day), and the northwest direction.

Beyond his cosmological and ritual roles, the Upanishadic tradition assigns Chandra a distinct place in the soul's journey after death. The Brihadaranyaka and Chandogya Upanishads describe the Pitriyana, the path of the ancestors, in which the departing soul ascends to the lunar realm and remains there until its accumulated merit is exhausted, then descends again to be reborn on earth — as distinct from the Devayana, the path of the gods, which bypasses the moon entirely for Brahmaloka without return. This makes Chandra the presiding deity of the threshold between death and rebirth, and connects him directly to the ancestors sustained by lunar soma in the shraddha rites — the same rites, notably, at the center of the Vikukshi episode in Ikshvaku's own chronicle.

Through Budha, Chandra becomes the root of the entire Lunar dynasty: Budha and the celestial nymph Urvashi produce Pururavas, whose line runs through Ayu, Nahusha, and Yayati, and then splits — through Yayati's son Puru toward Dushyanta, Bharata, Kuru, Shantanu, and ultimately the Pandavas and Kauravas of the Mahabharata; and through Yayati's son Yadu toward the Yadava line that eventually produces Krishna. The entire conflict of the Mahabharata, in this light, is a conflict within Chandra's own descendants.

Through his father Atri, Chandra connects upward to Brahma's original creative line — the same line this series opened with. Through his wives, the daughters of Daksha, he connects laterally to the vast Daksha-Kashyapa household that produces gods, demons, and every other class of being in the Puranic cosmos; Rohini herself is a sister of Aditi, mother of the twelve Adityas, meaning Chandra's own household and the solar household of Ikshvaku's line are joined through the same patriarch, Daksha, at one remove.
