I often hear people speaking that if I believe in God, and perform all the rituals associated in pleasing God, it will give mental satisfaction; it will give peace; it is the right way to salvation; it will give me true happiness etc etc. I just want to be in good mental health. I do not know whether religiousity is blind faith, but does it actually give peace or mental sanctity? If so, then how? What should I do to keep myself happy, and in proper mental orientation?
