The answer to these problems lies in making the instruments healthy, strong and well-trained. One must learn to observe, to produce sound waves, to relax and to be alert. Together, these four ways constitute complete education and can bring about a major transformation. It is through these ways that we can bring about lasting changes in the body, the breath, the speech and the mind. The first way relates to perception.
Indian philosophy is based on perception or seeing.
Its meaning has changed now. The philosophy being taught in colleges and universities is based on inference and reasoning but in ancient times it stood for direct apprehension. Not inference, not abstract reasoning, not causation, not universality or pervasiveness, but sheer apprehension. Today, we have lost the power to see and we fail to distinguish between thinking and seeing. Seeing then is something very important.
