The first problem we often face in meditation is restlessness in the body. There is always some irritating sensation which distracts us from sitting still for long periods of time. This inability to concentrate can be usually attributed to past indulgences like coffee, cigarettes and alcohol that have contaminated the body. By sustained effort as well as forswearing of any further excesses, the physical body has to be molded so it can become a willing receptacle (Adhar) which can bear the power and light which pours in during Yoga. A strong nervous system is a sine qua non for any spiritual transformation.
This post supplements a previous post Videha Dharana : fixing the mind outside the body, which discussed a method called Videha Dharana as per Sri Anirvan. The method is drawn from the Upanishads and can also be called PanchaTattva Dharana or contemplation on the five (pancha) elements (tattva) – namely earth, water, air, fire, ether. There is a similar technique in the Tantra texts called Bhuta-Shuddhi which is also outlined here.
One of the techniques Sri Aurobindo and the Mother recommended for meditation was contemplating on Akasha or Space. This has been discussed in the section on Widening of consciousness. The source of this technique lies in the Yoga Upanishads. Out of the 108 Upanishads, there are 21 which are known as the Yoga Upanishads. These contain various methods of Dharana (i.e. one-pointed concentration). This post contains a brief overview of these techniques as given in the book Dharana Darshan by Swami Niranjanananda Saraswati of the Bihar School of Yoga.
