IT is not possible to make a foundation in yoga if the mind is restless. The first thing needed is quiet in the mind. Also to merge the personal consciousness is not the first aim of the yoga: the first aim is to open it to a higher spiritual consciousness and for this also a quiet mind is the first need. ⁂ The first thing to do in the sadhana is to get a settled peace and silence in the mind. Otherwise you may have experiences, but nothing will be permanent. It is in the silent mind that the true consciousness can be built. page 635 , Letters on Yoga , volume 23 , SABCL |
There are two main things to be secured as the foundations of sadhana – the opening of the psychic being and the realisation of the Self above. For the opening of the psychic being, concentration on the Mother and self-offering to her are the direct way. The growth of Bhakti which you feel is the first sign of the psychic development. A sense of the Mother's presence or force or the remembrance of her supporting and strengthening you is the next sign. Eventually, the soul within begins to be active in aspiration and psychic perception guiding the mind to the right thoughts, the vital to the right movements and feelings, showing and rejecting all that has to be put away and turning the whole being in all its movements to the Divine alone. For the self-realisation, peace and silence of the mind are the first condition. Afterwards one begins to feel release, freedom, wideness, to live in a consciousness silent, tranquil, untouched by any or all things, existing everywhere and in all, one with or united with the Divine. Other experiences come on the way, or may come, such as the opening of the inner vision, the sense of the Force working within and various movements and phenomena of the working etc. One may also be conscious of ascents of the consciousness and descents of Force, Peace, Bliss or Light from above. page 636-37 , Letters on Yoga , volume 23 , SABCL |
Sadhana can go on in the dream or sleep state as well as in the waking. page 1481 , Letters on Yoga , volume 24 , SABCL |
