Om Sathguru Sri Seshadri Swamigal Thiruvadikkae
The Fourth Plane is the greatest hurdle of the spiritual Path, the crucial stage of the aspirant or pilgrim’s journey where all is gained or lost. Great as are the powers at his command, greater are the temptations to use them for his own gratification, to exhibit these powers for the sake of exhibitionism, fame, power, and glory. For the ego, fearing complete defeat rises to its highest, prodding and luring the pilgrim on to make selfish use of the powers lent to him. This is known as “Black night of the soul”.
The pilgrim on the fourth plane is permitted, however, to make use of his powers for purely unselfish motives, with no thought whatsoever of self and only for the sake of others.
“The senses are said to be superior (to the physical body); the mind is superior to the sense faculties; the intelligence is superior to the mind; but HE (the self) is superior to the intelligence”
(–Avathar Sri Seshadri Swamigal)
