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 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.
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.
Without going outside, you may know the whole world, without looking through the window, you may see the ways of heaven. The farther you go, the less you know. Thus the sage knows without traveling; he sees without looking; he works without doing.
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.
Who cares for your bhakti and mukti? Who cares what your scriptures say? I will go into a thousand hells cheerfully if I can rouse my countrymen, immersed in tamas, to stand on their own feet and be men inspired with the spirit of karma-yoga. I am a follower only of he or she who serves and helps others without caring for his own bhakti and mukti!
