The mind is weak on it's own. So Ramana Maharshi recommends a vegetarian diet plus breathing exercises in order to help focus the mind and also sitting in half lotus. He says Westerns are too "raja" -- their minds are too active in thought.
Ramana Maharshi focuses on LISTENING to the source of sound -- either japa or a mantra but most importantly the logos, the source of the I-thought.
Ramana Maharshi recognizes that kundalini and prana are part of establishing dyana (Ch'an) or a one-focused mind but he argues that the electromagnetic life force ultimately descends from the head going back to the heart, thereby getting to the root of the mind.
I recommend that you read Swami Vivekananda's Lectures on Yoga -- a series of books on raja and jnana yoga. Vivekananda explains that what Ramana Maharhsi practiced is the highest level of yoga -- nirvikalpi samadhi. When this is achieved the body is full of electromagnetic fields so greatly that it's just like deep sleep -- you don't feel the body and you're immersed in bliss. Most meditators never even achieve this first step to true meditation!
Ramana Maharshi teaches that when most yogis achieve nirvikalpi samadhi the ego takes over and the energy of the body is used for astral travel or for paranormal powers or for putting the body into a deep trance that stops time, etc. Ramana Maharshi states that these are just temporary abilities of the mind whereas ONLY by holding onto the "I"-thought as dyana, a focused concentration of one-thought, can the mind continue to go deeper into it's root within the body, whereby finally the self-awareness of the I-thought gets to its root, beyond the body. This can also happen by surrender or LISTENING to the source of a mantra or japa -- what Ramana Maharshi calls MOUNA SAMADHI (silence samadhi).
When the ego, attached to the body, is finally destroyed, after the heart stops for 10 minutes, then the mind can no longer accumulate karma and at death there is no reincarnation and while alive each breath and each thought AUTOMATICALLY resonates to pure consciousness.
What this means is that there is no evolution, that the only real truth is beyond time and space, that the whole universe is actually an illusion, etc.
But again since the mind is weak on its own normally, as Vivekananda details, the body must be harmonized so that nirvikalpi samadhi can be achieved. What the Taoists and Mahayana Buddhist and Gurdjieff teaches is that the harmonization of the body is based on an abstract process of the logos as 1-4-5 nonwestern music intervals. Gurdjieff uses the perfect 5th interval for his alchemy, detailed in "In Search of the Miraculous" while his "cirulation of energy" practice is the same as the small universe practice c.d. sold by http://springforestqigong.com and described in the book "Taoist Yoga: Alchemy and Immortality." As my masters thesis "epicenters of justice," readable online, documents, the 1-4-5 music intervals are actually the yin-yang and empty awareness harmonics. Mircea Eliade's book on yoga describes how the same small universe exercise was used in India as well.
So first practice the small universe in order to ionize your lower emotion electrochemicals so that more energy goes to your brain for stronger concentration. The active exercises that are sold from http://springforestqigong.com are the same as simple tai-chi and the secret of Gurdjieff's dances.
After you get the body harmonized then 20 minutes of full-lotus is worth 4 hours of any other exercise for enabling the harmonized electromagnetic energy to leave your third eye, thereby healing people, as your lower body takes in their unharmonized lower emotions -- anger, fear, sadness, worry, over-excitement.
This process is again impersonal and enabled by the 1-4-5 harmonics of the logos. An excellent book studying the origins of tantra in relation to the establishment of patriarchal monotheism and monism is WHEN GOD WAS A WOMAN by Merlin Stone. The original "god" is the snake-goddess -- the Tai-chi symbol -- the kundalini -- Pythagoras -- found as a statue in a cave from 80,000 BCE, Bushmen Africa.
