The Tapas and the other hard Yogas that were practiced in other Yugas do not work now. What is needed in this Yuga is giving, helping others.
Swami VivekanandaNot even the deepest sleep will give you such a rest as meditation can. The mind goes on jumping even in deepest sleep. Just those few moments in meditation your brain has almost stopped. ... You forget the body. ... You feel such pleasure in it. You become so light. This perfect rest we will get in meditation.
Swami VivekanandaAhimsa (non-killing), truthfulness, purity, mercy, and godliness are always to be kept.
Swami Vivekananda
