The activation and movement of Kundalini Shakti (Divine Serpent Power) is extremely difficult. This is because the flow has to be obstructed. One feels carefree and joyous when there is no discipline. The control, activation and arising of Kundalini power is increasingly difficult in that order. Not only does one have to imbibe control of senses, mind, thoughts, wealth, time, etc. but one has to become steadfast in it like the reins of horses, chains of a wild elephant and noose of a camel.
The 5 Divine Sheaths of the subtle human body.
The partitioning of the 5 sheaths has been presented in the categorization of the three bodies. These 3 are the gross, subtle and casual bodies. The gross body is made up of the food and Vital Force Sheath. The 5 elements and 5 Vital Forces ( Pranas) are embedded in it. The subtle body is made up of the mental and Intellectual Sheath. These 2 can be called conscious intellect and unconscious mind. The casual body is made up of the Bliss Sheath.
