The time is ripe now to inform one and all that whatever they are doing in the name of Meditation is not at all even concentration—let alone Meditation. Scores of people and so called Meditation centres mis-guide you, mis-handle you, and mis-lead you in the name of Meditation. You know not, even care to know not, what our scriptures say about it.
Do not be misled, open your eyes, see and learn carefully, question yourself what Meditation is, and then compare it with what our Yoga Shastras say about it. Never be a blind follower of any sect or people; think rationally. Be critical if you want to dive deep. Faith without wisdom has led many to nowhere.
