True spirituality directs all energies toward devotion to God, not toward satisfying personal desires in any form.Listen — Srila Prabhupada Uvaca
Prabhupāda: ...required to kill somebody, he'll do that—if it is required for his sense gratification. There are many instances that a woman is addicted to another man, and she has killed her husband, killed her son. Why? Sense gratification.
I have seen one woman, my Godbrother's wife, she killed her son for being implicated with another man. I have seen it. Nūnaṁ pramattaḥ kurute vikarma [SB 5.5.4]. Things which are not to be done, they do it.
Why? For the matter of sense gratification. They do it. That's a fact.
So therefore simply for sense gratification they are prepared to do anything. That means pāpa. It is the verdict of the court that when a man kills another man he becomes mad. Without becoming mad, a man cannot kill another man.
So everything is being done which is not sanctioned because for sense gratification. The whole world business is sense gratification. And at the end, when he's little spiritually inclined, he wants to satisfy senses by thinking artificially that "I shall become God." That is the greatest sense gratification. Because remaining a small living entity I have been hampered in my sense gratification.
Now let me become God so that there will be no restriction of my sense gratification. [Transl. Become Bhagavān.] Because he has failed to satisfy his senses remaining non-Bhagavān, now he wants to become Bhagavān. Yogī, that is also another sense gratification, that if I show some magic, if I can create little gold like this, hundreds and thousands of men will be after me and I shall live very nicely, just gratify my senses.
These things are going on practically. The man who is manufacturing gold, and so many rich people are coming to his disciples and he's begging for a motorcar. If he can create gold, why he cannot create a motorcar? This is going on.
