This Self who gives rise to all works, all desires, all odours, all tastes, who pervades the universe, who is beyond words, who is joy abiding, who is ever present in my heart, is Brahmn indeed. To him I shall attain when my ego dies.
Keep your body as clean as possible, your mind as clear as possible. That’s all you need. And do it in any way you can, in your own way. It doesn’t matter. And then you’ll be useful.
As the heat of a fire reduces wood to ashes, the fire of knowledge burns to ashes all karma. Nothing in this world purifies like spiritual wisdom. It is the perfection achieved in time through the path of yoga, the path which leads to the Self within.
Be at peace with yourself. If you are not at peace with yourself, you are at peace with nothing.
