Re: Nanak is the Guru; Nanak is the Lord Himself.
When one's mind quietens down away from the hustle bustle of worldly attention, one can train oneself to have rohani satsang within one's self.
Radha Soami use mainly gurbani from SGGS to propogate their own panth which circles around dehdhari gurus.
Many people have been taken for a ride into believing that dehdhari gurus are true masters. Read "fake babaas" posted by Surinder Kaur Cheema in SPN and you'll find how to sniff them out.
Yogi Bhajan explains what Guru ji (SGGS) says about Panch Shabad:-
Mantras are powerful tools for clearing and restructuring the subconscious mind. SAT NAM and its derivative SA TA NA MA are the two basic mantras taught by Yogi Bhajan to reorient the mind and thus open us up to the possibility of transformational change.
[FONT=Verdana, Arial, Helvetica, sans-serif]SAT NAM seeds the truth in our consciousness by waking us up to our divine identity. SAT NAM is the seed or bij mantra.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]SA TA NA MA incorporates the nuclear sounds of SAT NAM. SA TA NA MA uses the primal sounds to connect us to the evolutionary nature of existence itself. It is referred to as the panch shabd, which means a mantra with five sound currents. The fifth sound is "A." When we chant SA TA NA MA we imprint the evolutionary code of the universe into our human psyche.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]SA is the beginning, infinity, the totality of everything that ever was, is or will be.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]TA is life, existence and creativity that manifests from infinity.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]NA is death, change and the transformation of consciousness.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]MA is rebirth, regeneration and resurrection which allows us to consciously experience the joy of the infinite.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]SA TA NA MA is so primal that its impact on our psyche is like splitting an atom. The power of his mantra comes from the fact that it rearranges the subconscious mind at the most elementary level. It has the power to break habits and addictions because it accesses the level of the mind where habits are created.[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]Yogi Bhajan says that "Behavior patterns are the result of the radiance of the psyche and frequency of the magnetic field in relationship to the universal psyche and magnetic force." (*1)[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]The radiance of the psyche is dependent upon the active functioning of both the pituitary and pineal glands. The pituitary gland regulates the entire glandular system. The secretion of the pineal gland creates a pulsating radiance that activates the pituitary gland. The mind goes out of balance when the pineal gland is dormant. The imbalance makes it seem impossible to break mental and physical addictions. The mantra SA TA NA MA to a powerful tool to recreate balance in the mind.[/FONT]
