The Sadguru is realised and Aware of His own Self, the qualities of the Divine Soul (Paramatman) manifest in His Divine Self and through Him to you and from you to the rest of the souls in this world.
His divine vibrations spread Bliss, knowledge and truth to the world, and so even the most Tamasic souls i.e sad, nervous, confused and depressed souls, feel their spirit being lifted and elevated when they come in the presence of the Sadguru.
The Guru shakti is like a centrifugal force which draws all souls from its centre and align them towards bliss, enlightenment and knowledge. This Guru shakti also releases them from their worldly problems and their own negativity.
This Guru Shakti once again at the same time also becomes a centripetal force dissolving ignorance, mindsets and lack of faith, belief and trust in souls thereby unleashing the power of the soul. That is why the Sadguru is revered as the Bhava--roga--vaidya-- the physician of worldly diseases! The Sadguru treats
the mind and rids it of its illness of extreme desires and emotions, instability, doubts, confusion and self pity; the clean, clear and stable mind treats the body and rids it of physical illnesses.
The Sadguru thus makes your soul power come forth in its full splendour and reveals the Yogi in you — a divine being free in body, mind and spirit! On the holy day of Guru Poornima,
Lord Shiva reveals this truth - that all of you are meant to enjoy health, wealth, prosperity, peace, bliss, joy and contentment - not just fleetingly but at all times - because the Sadguru gives us the knowledge and assures us that all the above qualities of your soul are your birthright.
