Rabindranath Tagore 
SĀDHANĀ – The Realisation of life 

Compiled and translated by Tagore from his Bengali lectures, the book consists of eight essays, in which Tagore answers some of the most profound questions of life: Why did God create this world? Why would a Perfect Being, instead of remaining eternally concentrated in Himself, go through the trouble of manifesting the Universe? Why does evil exist? Do love and beauty have a purpose?
