Doing something wrong from a moral or material standpoint is not the only meaning of temptation. Forgetting your soul by becoming too engrossed in the body and its comforts is temptation too.
Sri Sri Paramahansa Yogananda
The soul trapped in the body – when the body tempts you with worldly pleasure and falling in the trap is also a sin.
There is a certain class of soul who will say God gave you a body to enjoy so enjoy as much as you can! From that stand point not enjoying is a sin
But the atman is not the body. Just living in the atman without the body is true deep joy
Bhavin
