Srimad Bhagavatam Canto 09, Chapter 14, Text 03

SB 9.14.3

tasya drgbhyo ’bhavat putrah
 somo ’mrtamayah kila
viprausadhy-udu-gananam
 brahmana kalpitah patih
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
From Atri’s tears of jubilation was born a son named Soma, the moon, who was full of soothing rays. Lord Brahma appointed him the director of the brahmanas, drugs and luminaries.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
According to the Vedic description, Soma, the moon-god, was born from the mind of the Supreme Personality of Godhead (candrama manaso jatah). But here we find that Soma was born from the tears in the eyes of Atri. This appears contradictory to the Vedic information, but actually it is not, for this birth of the moon is understood to have taken place in another millennium. When tears appear in the eyes because of jubilation, the tears are soothing. Srila Visvanatha Cakravarti Thakura says, drgbhya anandasrubhya ata evamrtamayah: “Here the word drgbhyah means ‘from tears of jubilation.’ Therefore the moon-god is called amrtamayah, ‘full of soothing rays.’” In the Fourth Canto of Srimad-Bhagavatam (4.1.15) we find this verse:
 
atreh patny anasuya triñ
 jajñe suyasasah sutan
dattam durvasasam somam
 atmesa-brahma-sambhavan
 
This verse describes that Anasuya, the wife of Atri Rsi, bore three sons — Soma, Durvasa and Dattatreya. It is said that at the time of conception Anasuya was impregnated by the tears of Atri.
