Srimad-Bhagavatam: Canto 1 - Chapter 1 - Verse 39

Sanskrit:

नेयं शोभिष्यते तत्र यथेदानीं गदाधर ।त्वत्पदैरङ्किता भाति स्वलक्षणविलक्षितै: ॥ ३९ ॥

ITRANS:

neyaṁ śobhiṣyate tatrayathedānīṁ gadādharatvat-padair aṅkitā bhātisva-lakṣaṇa-vilakṣitaiḥ

Translation:

O Gadādhara [Kṛṣṇa], our kingdom is now being marked by the impressions of Your feet, and therefore it appears beautiful. But when You leave, it will no longer be so.

Purport:

There are certain particular marks on the feet of the Lord which distinguish the Lord from others. The marks of a flag, thunderbolt, and instrument to drive an elephant, umbrella, lotus, disc, etc., are on the bottom of the Lord’s feet. These marks are impressed upon the soft dust of the land where the Lord traverses. The land of Hastināpura was thus marked while Lord Śrī Kṛṣṇa was there with the Pāṇḍavas, and the kingdom of the Pāṇḍavas thus flourished by such auspicious signs. Kuntīdevī pointed out these distinguished features and was afraid of ill luck in the absence of the Lord.
