All action of Sattva, a modification of Prakriti characterised by light and happiness, is for the soul. When Sattva is free from egoism and illuminated with the pure intelligence of Purusha, it is called the self-centred one, because in that state it becomes independent of all relations.
Have faith in Guru, in his teachings, and in the surety that you can get free. Think day and night that this universe is zero, only God is. Have intense desire to get free.
Perfection does not come from belief or faith. Talk does not count for anything. Parrots can do that. Perfection comes through the disinterested performance of action.
The first sign that you are becoming religious is that you are becoming cheerful. When a man is gloomy, that may be dyspepsia, but it is not religion. Misery is caused by sin, and by no other cause. What business have you with clouded faces? It is terrible. If you have a clouded face, do not go out that day, shut yourself up in your room. What right have you to carry this disease out into the world?
Let us work without desire for name or fame or rule over others. Let us be free from the triple bonds of lust, greed of gain, and anger. And this truth is with us!
We must recognise that duty and morality vary under different circumstances; not that the man who resists evil is doing what is always and in itself wrong, but that in the different circumstances in which he is placed it may become even his duty to resist evil.
