SB 7.15.19

asantustasya viprasya
 tejo vidya tapo yasah
sravantindriya-laulyena
 jñanam caivavakiryate
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Because of greed for the sake of the senses, the spiritual strength, education, austerity and reputation of a devotee or brahmana who is not self-satisfied dwindle, and his knowledge gradually vanishes.
