Verse
गामाविश्य च भूतानि धारयाम्यहमोजसा ।पुष्णामि चौषधीः सर्वाः सोमो भूत्वा रसात्मकः ॥
I have entered into this form of earth (and am the spirit of its material force) and sustain by My might these multitudes. I am the godhead of Soma who by the rasa (the sap in the earth-mother) nourishes all plants and trees.
Gītā 15·13
