To be aware of a single shortcoming within oneself is more useful than to be aware of a thousand in somebody else.

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.
In ancient times, any man rising up above the common people tried to shape his life according to his principles; it is no longer like than now; it is (because) for the ancients, moral was a principle of inner life, whereas in our days, most of the time one is content to adhere to an official moral, that we recognize in theory, but that one does not care to put into practice.
According to Krishnamacharya , practice and knowledge must always go together. He used to say, practice without right knowledge of theory is blind. This is also because without right knowledge, one can mindfully do a wrong practice.
