lyrics
(1)
 [bad word] charana-padma, kevala-bhakati-sadma
bando mui savadhana mate
jahara prasade bhai, e bhava toriya jai,
krishna-prapti hoy jaha ha'te

(1) The lotus feet of our spiritual master are the only way by which we can attain pure devotional service. I bow to his lotus feet with great awe and reverence. By his grace one can cross the ocean of material suffering and obtain the mercy of Krishna.

(2)
 [bad word] mukha-padma-vakya, chittete koriya aikya
ar na koriho mane asha
 [bad word] charane rati, ei se uttama-gati
je prasade pure sarva asha

(2) My only wish is to have my consciousness purified by the words emanating from his lotus mouth. Attachment to his lotus feet is the perfection that fulfills all desires.

(3)
chakhu-dan dilo jei, janme janme prabhu sei
divya-jnan hride [bad word] 
prema-bhakti jaha hoite, avidya vinasha jate
vede [bad word] jahara chariot

(3) He opens my darkened eyes and fills my heart with transcendental knowledge. He is my Lord birth after birth. From him ecstatic prema emanates; by him ignorance is destroyed. The Vedic scriptures sing of his character.

(4)
 [bad word] [bad word] sindhu, adhama janara bandhu
lokanath lokera jivana
ha ha prabhu koro doya, deho more pada-chaya
ebe jasha ghushuk tribhavana

(4) Our spiritual master is the ocean of mercy, the friend of the poor, and the lord and master of the devotees. O master! Be merciful unto me. Give me the shade of your lotus feet. Your fame is spread all over the three worlds. We take shelter of your lotus feet. You are the friend of the most fallen.

jaya jaya prabhupada! jaya jaya prabhupada!

All glories to Srila Prabhupada!
