Is it necessary to practice all these asanas, further and further? Is it necessary to develop scientific researches further and further? To a yogi, the body is a laboratory, a field of experiments and perpetual researches.

Anything physical is always changing, therefore, its reality is not constant, not eternal.

What I was is unimportant, what I am now is important.

Yoga is a way of life; it is an art, a science, a philosophy.

The challenge of yoga is to go beyond our limits - within reason. We continually expand the frame of the mind by using the canvas of the body. It is as if you were to stretch a canvas more and create a larger surface for a painting. But we must respect the present form of our body. If you pull too much at once, we will rip the canvas. If the practice of today damages the practice of tomorrow, it is not correct practice.

Our greed comes from our fear that we will not have enough - whether it is money or love that we grasp. Yoga teaches us to let go of these fears and so to realize the abundance around us and within us.

Your body exists in the past and your mind exists in the future. In yoga, they come together in the present.
