Some upanishads state that reading them help to get rid of sins. This
need knowledge to prepare question by onself on the idea of good and
bad, right and wrong, pure and impure, violence and nonviolence etc..
by a common priniciple called neti, neti ie this isn't, this isn't.
Concepts of duallity or partiallity never work with spiritual
progress. Nutrality is what needed one to come above the level of
fear. Belief or Imanagination dont work, answers found by one can
verify with upanishads.
