Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 28

Sanskrit:

राम राम महाबाहो न जाने तव विक्रमम् ।यस्यैकांशेन विधृता जगती जगत: पते ॥ २८ ॥

ITRANS:

rāma rāma mahā-bāhona jāne tava vikramamyasyaikāṁśena vidhṛtājagatī jagataḥ pate

Translation:

[Goddess Yamunā said:] Rāma, Rāma, O mighty-armed one! I know nothing of Your prowess. With a single portion of Yourself You hold up the earth, O Lord of the universe.

Purport:

The phrase ekāṁśena (“with a single portion”) refers to the Lord’s expansion as Śeṣa. This is confirmed by the ācāryas.
