Manifested Brahma is the ‘I am’, whatever principle is prior to the utterance of sound, that principle proclaims by itself. What I insists is that you must stabilize in that state. The recitation of the mantra ‘So Hum’ must be for a very long time, it is prior to words. When that ‘So Hum’ principle, is pleased, that principle, represented by these words, expounds knowledge.
The ‘So Hum’ Japa is incessantly going on in your pulse, indicating ‘I am’ get in tune with it by recitation. That ‘So Hum’ energy without words is the raw material of incarnations and the incarnations are the hoardings of the primary principle. The primordial principle is ‘Parabrahman’; its advertisement is done by movement, the stirrings of ‘So Hum’. By its movement it is praising the primordial principle, that advertising material is the ‘Moolmaya’ (Primary Illusion). That incarnating principle – the ‘Moolmaya’– gives knowledge to the incarnated.
