Stretching [and] yoga [are] very helpful. All of these things - they really do help. Good food and a lot of sleep. And reading - reading good books. Sometimes movies - although a lot of the movies are difficult.
Thus to act under the guidance coming from above, this is one side of the sadhana, the dynamic side. The other one is the discrimination between the Purusha and the Prakriti. The Purusha will calmly observe, give sanction, choose, but will realise that all this does not belong to him - all these are outside him. This is the static side of the sadhana. These two aspects constitute the basis of Yoga.
Yoga means to bind back, unite. To bring the body and the soul together. For this reason the practice of yoga is a holy endeavor and the teaching of it to our people a very high calling.
Yoga exercises are excellent; the speaker does them every day, for an hour or more; but that is merely physical exercise, to keep the body healthy, and so on.
The chief helps in this liberation are Abhyasa and Vairagya. Vairagya is non - attachment to life, because it is the will to enjoy that brings all this bondage in its train; and Abhyasa is constant practice of any one of the Yogas.
