Detachment is not indifference. it is the prerequisite for effective involvement. Often what we think is best for others is distorted by our attachments to our opinions. We want others to be happy in the way we think they should be happy. It is only when we want nothing for ourselves that we are able to see clearly into others needs and understand how to serve them.
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.
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.
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!
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.
