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.
If you practice in accord with your individual capacity, little by little you will find more pleasure and joy in it. As you gain inner strength, your positive actions will gain in profundity and scope.
The nature of the mind is such that if certain mental qualities are developed on a sound basis, they not only remain, but they also increase. In fact, once properly developed, the mind's good qualities eventually increase indefinitely. Therefore spiritual practice brings us long-term happiness and inner strength.
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.
Life creeps slowly upward.... When some forgotten inventor of the older world smote his rival or enemy with a branch of wood and found that it was good and thereafter made a practice of smiting rivals and enemies with branches of wood, then, and on that day, artificiality may be said to have begun. Then, and on that day, was begun a revolution destined to change the history of life. Then, and on that day, was laid the cornerstone of that most tremendous of artifices, CIVILIZATION!
We have limited time in our life, therefore we should try to teach ourselves, not to teach others. We should conquer ourselves, rather than conquer others. Whether coming or going, standing, sitting or lying down, our mind should be focused in this way. If we practise like this and develop mindfulness continuously, wisdom arises quickly and this is a fast way of practice.
The business of every art is to bring something into existence, and the practice of an art involves the study of how to bring into existence something which is capable of having such an existence and has its efficient cause in the maker and not in itself.
