Every child arrives into the world bearing the burden of consequences that were not carried to completion in previous lives. The child does not drop from the lap of Nature as a streak of lightning from the clouds. It is born in this world in order to experience the beneficial and the malignant consequences that are the products of its own acts in past lives. This is the explanation for the differences that are evident among men. This is the principle of Karma.

– Sathya Sai Vahini, Ch 13: "The Avatar as Guru".

Knowledge without action is useless; action without knowledge is foolish. – Baba
