Pure devotees are so absorbed in thought of Kṛṣṇa that they have no other engagement; although they may seem to think or act otherwise, they are always thinking of Kṛṣṇa. The smile of such a Kṛṣṇa conscious person is so attractive that simply by smiling he wins so many admirers, disciples and followers.
(Srila Prabhupada purport on Śrīmad-Bhāgavatam 3.22.21 | 1974 Edition)
