man-mantropāsakā viprā ye mad-ucchiṣṭabhojinaḥ
mām eva nityaṁ dhyāyante te mat-prāṇādhikāḥ priyāḥ
Vipras who worship Me through My mantra and eat My remnants always meditate upon Me alone. They are more dear to Me than My very life.
tad-upasparśa-mātreṇa pūte vāyuś ca pāvakaḥ
kaler daśa-sahasrāṇi mad-bhaktāḥ santi bhū-tale
Merely by touching them the wind and air become purified. My devotees will be on the surface of the earth for ten thousand [years] in Kali-yuga.
eka-varṇā bhaviṣyanti mad-bhakteṣu gateṣu ca
mad-bhakta-śūnyā pṛthvī sā kali-grastā bhaviṣyati
After My devotees depart [from the world], there will only be people of one varṇa. Devoid of My devotees, the earth will be seized by Kali.
