To someone who asked which of the chakras was the best to focus on in meditation.
Meditation on a specific chakra can confine and limit the yogis awareness. What happens spontaneously alone is correct and worthy of attention. I wrote in Soham Yoga:
“Sometimes during meditation you may spontaneously become more aware of some point or area of the body, and that is all right, but keep the focus of your attention on the breath and your intonations of Soham, letting whatever happens, happen, letting the subtle energy (shakti) of Soham move where it will and energize and awaken whatever needs energizing and awakening at that moment. Since everything is formed of prana, the essence of breath, intoning Soham in time with the breath effects every part and aspect of our being, physical, astral, and causal.
There is an exception to this. On occasion, such as at the very beginning of meditation or when during the rest of the day you find your attention drifting from the breath and Soham, it can be helpful to make yourself very gently (lest you give yourself a headache from tension) aware of your entire brain (Sahasrara) area, feeling that the breath and Soham intonations are taking place there.
A short time of this awareness–just the duration of a few breaths–is sufficient, because subsequent practice of Soham sadhana will result in spontaneous Sahasrara awareness whenever that is best.”
