3.25.39

na karhicin mat-parāḥ śānta-rūpe naṅkṣyanti no me 'nimiṣo leḍhi hetiḥ /
yeṣām ahaṃ priya ātmā sutaś ca sakhā guruḥ suhṛdo daivam iṣṭam //

38. O mother that hast attained a perfectly tranquil state of mind, those that are devoted to Me never fall from that state of blissfulness in Vaikuntha which consists of _suddha satva_; My weapon in the form of Time does not touch them (taste or affect them); for, of them I am the beloved soul; to them I am the son, friend, preceptor, well-wisher and beloved Deity.
