SB 2.07.53 "If the jīva constantly describes māyā in relation to the Lord, remembers māyā or hears about māyā with proper faith, he will not be bewildered by māyā." -Viśvanātha Cakravartī Thakura
It is true that by practicing restraint of the senses by the yoga system one can get relief from the disturbances of desire and lust, but this is not sufficient to give satisfaction to the soul, for this [satisfaction] is derived from devotional service to the Personality of Godhead. Śrīmad Bhāgavatam 1.6.35
-Viśvanātha Cakravartī Thakura
What are some of the causes of distraction from the path of pure faith?
Śrīla Prabhupāda mentions the following: not properly accepting the seed or the spiritual master's instruction, not watering the seed properly, and not uprooting unwanted creepers and therefore succumbing to their influence. (Derived from purports of Śrī Caitanya Caritāmrta, Madhya Līlā 19.155-159)
