In order to know life in its entirety it becomes mandatory to understand, follow and live life on the terms of Sanatana Dharma. It will be worthwhile to understand the structure of the Dharma. The propounders of the Dharma and the values it offers to the genuine follower of the Dharma.
Sanatana Dharma is vast as the blue ocean. You cannot measure its extent, neither can you fathom its depth. It defines the whole of the universe within its fold. A person who understand Sanatana Dharma, the one who has realized Sanatana Dharma, becomes immortal. For him, there remains no unfinished duties.
