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 human body (Microcosm) is said to be a small sample of the cosmos (Macrocosm). The entire body of a big tree is hidden in a tiny seed. In a small sperm lies the cast of the entire human body. The manner in which the mutual attraction and activities of the planets of the solar system are executed, can be seen albeit at a microlevel within the atomic family represented by electrons, neutrons etc. In the same way the entire cosmos can be seen in a microform within this small human body.
