‘Anu’ means a molecule. Our attention is always attracted towards outside happenings and it is an impossibility to take this attention inside. That is why something has to happen within us to attract that attention inside. We cannot force our attention inside, so people try, normally, the anuvopai is that what you call Ashtanga Yoga and other Yogas, by which they try separating themselves from myth, from darkness; for which you need very astute, honest, sincere people, very young celibate, innocent people, those who have to live in the forest with their Gurus. So they keep out their attention, which is called as nirodha (restraint). They stop their attention spreading itself. They concentrate their attention with the help of a Realised soul. These are the people who are detached, veetragas. Not that you have to run way from anywhere, but living in the society only you can achieve it through our Sahaja Yoga or Mahayoga. This is shaktopai.
