Mula = Root, Origin, Essence
Adhara = Basis, Foundation
Just as the womb of the mother creates the basic requirement for the growth of the embryo, the Muladhara Chakra forms the basis and the starting point for our spiritual development. It is the foundation from which we climb the ladder of the Chakras; the root from which we receive the nourishment for our spiritual development. For this reason, and because it lies at the lowest point of the spinal column below the Coccyx, it also bears the name "Root Chakra".
Everyone admires the leaves and flowers of a plant, but hardly anyone takes any notice of the roots that lie hidden in the darkness of the earth. But the roots form the basis of the vegetation. From the sustenance received from the roots the sprout gains the power to penetrate the dark soil, grow upwards towards the sun and produce flowers, fruit and seeds.
Kundalini Shakti (spiritual energy) has its roots in the Muladhara Chakra, but it is in a deep, motionless sleep. When we awaken this slumbering potential that lies within the Muladhara Chakra we are able to work our way towards the light of knowledge and attain the fruit of Self-Realisation.
Sri Mahaprabhuji described the process of the development of consciousness from the Muladhara Chakra to Supreme Consciousness in a Bhajan. In this Bhajan he mentions a Yoga technique through which we can awaken the Kundalini Shakti in the Muladhara Chakra. This Yoga technique is known as "Yoga Nidra", the conscious "sleep of the Yogi" , which is able to give us deep and beautiful experiences at a higher level of consciousness. It is also practised as a deep relaxation technique.
