2.3.23

jīvañ chavo bhāgavatāṅghrireṇuṃ na jātu martyo 'bhilabheta yastu /
śrīviṣṇupadyā manujastulasyāḥ śvasañ chavo yastu na veda gandham //

23. He who never wears (is bathed in) the dust of the feet of the Lord's devotees, is a dead man even while alive; he who has not known the fragrance of the _tulasi_ on Hari's feet, is a corpse, although he may be breathing.
