Thank you for your question. However, it is not an easy question to answer but nevertheless I’ll try to offer some of sastric advice and some of my personal experience of whatever little value that may be. First of all here is an straightforward and excellent explanation which summons it all up by Srila Bhaktissidhanta Saraswati Thakur in his Amrita-vani “immortal instructions”:
33. Can one be attached to sense gratification even after taking initiation?
“The process of attaining transcendental knowledge is called initiation. We should know that the Supreme Lord is the transcendental Absolute Truth, we are His eternal servants, and we have no duty other than to serve Him. Knowing this is actual initiation. The absence of this understanding is ignorance. At present, there is a controversy about the word “initiation”. People proudly claim that they have taken initiation from a bona fide spiritual master, but how can they maintain material attachment even after taking initiation? How can they desire to make advancement in material life? If they don’t learn about their relationship with the Lord, independent and proud people uselessly brag about their initiations. Rather than treating their spiritual master as if he were as good as God, they treat him as their disciple, fit to be their order-supplier. Considering the guru an ordinary mortal being, these persons become offenders at his lotus feet.
