The human body is the most excellent boon conferred by the Almighty and the person who comprehends his own body completely, realises the subtle mysteries of the entire universe. All universal faculties are concentrated as the force of life inside a human body which the scriptures term as the vital power (Pran Shakti). The condensed form of the same vital forces is known as 'Kundalini Shakti' which is the rock bottom of all the energies and power of action inherent in a human being. As this divine power remains dormant just like the coil of a snake, it has been designated as 'Kundalini Shakti' or the 'serpent Power'. For the purpose of Self-Realisation, a man through his 'Sushumna' (spine) tries to uplift this Kundalini Shakti in an upward tract and crossing all the Chakras (subtle spinal centres) tries to unite it with 'Sahastrar'.
When the aspirant emerges successful in his endeavour, he gets divine vision and visualising his real form though his divine eye, he feels overwhelmed with ecstasy and thus liberates himself from the corporeal bondages of life and death.
