Kundalini is a very important concept in Sakta tradition. The cosmic energy is dorment in mooladhara of sadhaka(Devotee)
and by means of intense meditation and sadhana it is awaken and raises to Sahsrara kamala(thousand petalled lotus) which
is the final destination, passing through various chakras(plexus). This process takes many years of intense sadhana. In each
chakra, Devi is worshipped in a different form.The Union of Siva and sakti takes place in the sahsradalakamalam. If a
devotee is able to reach that level he becomes beyond births and deaths.
Let us start from the scratch.Mooladhara is the basic plexus and it is situated at the base of susumna, described as
four petalled lotus and constituted the earth element. The Cosmic Sakthi, Tripurasundari, or energy, is dorment like a coiled
serpent. The second plexus is six petalled Svadhishtana chakra which is situated below the gentitals and fire is the
constituent element. Above Svadhishtana chakra, at the level of navel is placed the ten petalled Manipoora chakra with water
is the element. At the level of heart situates Anahatha chakra with twelve petals and air as the element. Below the level
of throat is Visuddhi chakra and it is sixteen petalled and element is Akaasa. The sixth Plexus is Ajna chakra with two petals
constituting the element of Mind(Manas) which includes five organs of knowledge and five organs of action.
When by scientific practice of pranayaama and meditation the kundalilni(the cosmic energy) which is dorment at mooladhaara
is awaken and ascents to the higher level of plexus by means of power of concentaration generated by japa and pranayaama coupled
with sadhana. The final stage is when Shakthi in the form of cosmic energy reaches the brain(Sahasradalakamala) to unite with
the paramaathma, Siva.
This note is very skeletal, I know. Those who are interested are recommended to go through "The Serpent Power" by Sir
John Woodrof, more popularly known as Arthur Avlon. Web sites are devoted to this subject and URLs are given in the next
