It is said to be the root centre of physical experience, the seat of Kundalini, the latent cosmic energy or shakti that resides in every living being.
After practice of many different forms of concentration the process of arousing the Kundalini should be practiced.
The roused Kundalini goes to the Sahasrara after absorbing all principles lying in the chakras where Samandhi is attained. At this stage consciousness is only in the form of Kundalini.
