Surely what are all with you are subject to leave but what the Almighty pleases to gift will ever be with you by centuries and centuries till the end of this earth.
Everything in earth has got two faces. One is physical and the other is spiritual. The physical is subject to pass. But the spiritual is eternal.
Spiritual knowledge is the treasure of priceless divine gift, which speaks with divine strength even after death.
Your rich mind is the gift of the Almighty.
