Srimad Bhagavatam Canto 06, Chapter 17, Text 14

SB 6.17.14

nayam arhati vaikuntha-
 pada-mulopasarpanam
sambhavita-matih stabdhah
 sadhubhih paryupasitam
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
This person is puffed up because of his achievements, thinking, “I am the best.” He does not deserve to approach the shelter of Lord Visnu’s lotus feet, which are worshiped by all saintly persons, for he is impudent, thinking himself greatly important.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
If a devotee thinks that he is very much advanced in devotional service, he is considered puffed up and unfit to sit beneath the shelter of the Lord’s lotus feet. Again, this instruction by Lord Caitanya is applicable:
 
trnad api sunicena
 taror api sahisnuna
amanina manadena
 kirtaniyah sada harih
 
“One should chant the holy name of the Lord in a humble state of mind, thinking oneself lower than the straw in the street; one should be more tolerant than a tree, devoid of all sense of false prestige and ready to offer all respect to others. In such a state of mind one can chant the holy name of the Lord constantly.” Unless one is humble and meek, one cannot qualify to sit at the lotus feet of the Lord.
