To lead a life of faith and piety in this world is to give proof of tremendous sacrifice. It amounts to renouncing an apparent and visible heaven for the sake of a hidden, invisible heaven. This also means succeeding in the most difficult of tests, i.e. when man recognises the Truth on the strength of abstract arguments and then he turns his life in that direction, though there is no pressure on him to do so. Those who exhibit such awareness (of truth) and perform such actions truly deserve to be admitted to gardens of eternal comfort and pleasure.
