The desire of your vital being is towards work. And the vital being won't find any interest in yoga so long as you do not have any experience of the higher and fuller life that is in yoga. As long as this experience is not there, the vital being will not find any interest.
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 is a generic name for any discipline by which one attempts to pass out of the limits of one's ordinary mental consciousness into a greater spiritual consciousness.
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.
Anything that is secret and mysterious in this system of Yoga should be at once rejected. The best guide in life is strength. In spirituality, as in all other matters, discard everything that weakens you. Have nothing to do with it. Mystery-mongering weakens the human brain. It has well-nigh destroyed Yoga, one of the grandest of sciences
The higher Truth is all the time working in us but through the lower power - Aparashakti. It is when we become conscious of the play of this higher Power then only yoga begins.
