"The Beginning of Spiritual Life" by Siddhaswarupananda Paramahamsa
It is important to know that you are not material in essence but rather an eternal spark of life. But such knowledge is just the beginning of a long and arduous journey toward a perfect understanding of your identity.
Everyone is suffering. Everyone experiences birth, disease, old age and death. Everyone experiences fear, loneliness, emptiness, confusion, mental agitation, and heartache. Yet a fool, despite the fact that he keeps getting his teeth kicked in, never thinks twice about the whole thing. An intelligent person sees he is suffering and wants to know why. He thus becomes motivated to seek a solution to the problems of life. He seeks liberation. That is the beginning of spiritual life.
