I am convinced that courage is the most important of all the virtues. Because without courage, you cannot practice any other virtue consistently. You can be kind for a while; you can be generous for a while; you can be just for a while, or merciful for a while, even loving for a while. But it is only with courage that you can be persistently and insistently kind and generous and fair.
The Master said, "To study, and then in a timely fashion to practice what you have learned - is this not satisfying? To have companions arrive from afar - is this not a joy? To remain unrecognized by others and yet remain free of resentment - is this not the mark of the gentleman?"
Ahimsa is the highest duty. Even if we cannot practice it in full, we must try to understand its spirit and refrain as far as is humanly possible from violence.
Krishnamacharya's personal practice was always with long deep breathing and mental focus. Observe the position of his head, the lower abdomen and his mental focus. He was always concentrated on the inner alignment through breath.
Does one scent appeal more than another? Do you prefer this flavor, or that feeling? Is your practice sacred and your work profane? Then your mind is separated: from itself, from oneness, from the Tao.
If you desire to be pure, have firm faith, and slowly go on with your devotional practices without wasting your energy in useless scriptural discussions and arguments. Your little brain will otherwise be muddled.
