Answers
If you truly believe in something and stay completely focussed, immersed in it, make it as the utmost purpose of your life, tune your mind to stay with it unflinchingly and nothing else matters in your life, you can said to be lost in perpetual contemplation of it.
In such a case, you will remain unaffected by anything else and nothing can deter you. Your "body, mind and soul" are attuned to it.
