Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 21

Sanskrit:

धिष्ण्यानामस्म्यहं मेरुर्गहनानां हिमालय: ।वनस्पतीनामश्वत्थ ओषधीनामहं यव: ॥ २१ ॥

ITRANS:

dhiṣṇyānām asmy ahaṁ merurgahanānāṁ himālayaḥvanaspatīnām aśvatthaoṣadhīnām ahaṁ yavaḥ

Translation:

Among residences I am Mount Sumeru, and of impervious places I am the Himālayas. Among trees I am the holy fig tree, and among plants I am those that bear grains.

Purport:

Oṣadhīnām here indicates those plants that fructify once and then die. Among them, those that give grains, which sustain human life, represent Kṛṣṇa. Without grains it is not possible to produce milk products, nor can one properly perform Vedic fire sacrifices without offerings of grains.
