In Muladhara is the first primary chakra according to the Hindu Tantric tradition (Shakta).

Muladhara is positioned close to anus, at the perineum, and it has four petals that match the vrittis of greatest joy, natural pleasure, delight in controlling passion, and blissfulness in concentration.

In Samkhya philosophy, the concept of Muladhara is that of moola prakriti, the metaphysical basis of material existence. Muladhara is the chakra that draws down spritual energy and causes it to assume a physical existence. It is like the negative pole in an electrical circuit, which provides the potential for the evolution of form.

Within this chakra resides sleeps the kundalini shakti, the great spiritual potential, waiting to be aroused and brought back up to the source from which it originated, Brahman.

Muladhara is the base from which the 3 main psychic channels, nadis, ida, pingala and sushumna, emerge.

It is related to the physical processes of reproduction and excretion, and also to the various fear and guilt complexes associated with them. All a person's Samskaras ( potential karma ), are expressed here, in a physical form.
