For this kind of Sadhana, no Asana, no room is needed. This Sadhana is suitable for men of the world who are intelligent. This is the work combined with Jnana. The Self light of Para Bhahman is appearing as mind and universe. World is nothing but mind.
World is a long dream.
I have given you the essence of Vedanta or Jnana Yoga in a nut-shell. Proclaim it everywhere boldly. Shine as Brahman. Move about boldly, my dear Jyoti.
