Shrividya is a secret, ritual-based religious tradition
practiced in southern India, with the goddess Lalita Tripurasundari as its main
deity.
The Shrichakra, a specific sym bolic diagram (yantra) formed
of a sequence of interlocking triangles, is used ritually in the Shrividya
tradition.
The Shrichakra ritual, also known as samhara krama, is a
systematic ritual that involves the destruction of the perceivable world and
all illusions of duality in order to achieve union with the single true
reality.
The practice of kundalini yoga, which is based on the tantric
concept of the subtle body—the six psychic centers (chakras) running along the
spine—seeks to achieve ultimate union within the aspirant's own body by
bringing together the microcosmic forms of the deities Shiva and Shakti that
exist within the body, is the interior counterpart to this exterior ritual.

1990, for a thorough examination of the Shrividya tradition.
