Om Swami
How can I become pure without elaborate rituals?
Honesty leads to purity and truth
Don't get too caught up in puja and punya (merit) and other good acts; just be honest about your emotions and your actions. Honesty leads to purity and to truth.
Honesty will lead to purity and to truth. Be transparent and the rest will be taken care of. Wherever there is honesty, you don't need God; honesty is God.
