You have to grow from the inside out. None can teach you, none can make you spiritual. There is no other teacher but your own soul. – Swami Vivekananda
The Vedanta recognizes no sin it only recognizes error. And the greatest error, says the Vedanta is to say that you are weak, that you are a sinner, a miserable creature, and that you have no power and you cannot do this and that. – Swami Vivekananda
