“ This body and mind are just temporary happenings. Is the awareness of that not inspiration enough to long for something beyond? ”
The secret of health for both mind and body is not to mourn for the past, worry about the future, or anticipate troubles, but to live in the present moment wisely and earnestly.
Your problem is just this - your body and your mind are not taking instructions from you, that's all.
Free from expectations and the sense of ownership, with mind and intellect fully controlled, they incur no sin, even though performing actions by one's body.
Once there is a distance between you and your body, once there is a distance between you and your mind this is the end of suffering, this being cannot suffer any more; question of conflict doesn't arise.
You can use this mind as a ladder to the Divine, or you can use it to trap yourself into this little body and feel like a refugee on this planet
