dhisnyanam asmy aham merur
osadhinam aham yavah
Among residences I am Mount Sumeru, and of impervious places I am the Himalayas. Among trees I am the holy fig tree, and among plants I am those that bear grains.
Osadhinam here indicates those plants that fructify once and then die. Among them, those that give grains, which sustain human life, represent Krsna. Without grains it is not possible to produce milk products, nor can one properly perform Vedic fire sacrifices without offerings of grains.
