The benefits of knowledge can only be realized in practice.

If we have a correct theory but merely prate about it, pigeonhole it and do not put it into practice, then that theory, however good, is of no significance.

Science is the captain, and practice the soldiers.

Through practice comes Yoga, through Yoga comes knowledge, through knowledge love, and through love bliss.

Practice is absolutely necessary. You may sit down and listen to me by the hour every day, but if you do not practice, you will not get one step further. It all depends on practice.

If you want to know the taste of a pear, you must change the pear by eating it yourself. If you want to know the theory and methods of revolution, you must take part in revolution. All genuine knowledge originates in direct experience.
