The simran by the tongue, by the throat, by the heart or from the navel centre is respectively more efficacious. That simran is best which leads to inner concentration... Simran should be done in accordance with the instructions of a master whose own soul has merged in god. Such simran will result in the greatest good because it makes use of thought-transference (master to disciple), which removes all obstacles that confront us in our transport to the upper regions. Thus the soul receives personal and constant guidance on the difficult path leading to the upper spiritual regions. Simran should be done by sitting in a comfortable posture, by concentrating the attention at the centre between the two eyebrows, and by lovingly and devotedly repeating the holy names with the tongue of the soul. By doing this, the wavering mind becomes steady and one is able to achieve concentration.
