Svadhishthana Chakra is a chakra that is located at the base
of the spine.
The svadhishthana chakra is one of the six psychic centers
(chakras) thought to exist in the subtle body, according to several yoga
schools and the esoteric ritual tradition known as tantra.
The subtle body is a physiological system that is thought to
exist on a separate level than coarse matter yet has certain similarities with
it.
It is shown as a group of six mental centers, which are
envisioned as multipetaled lotus flowers that run approximately parallel to the
spine and are joined by three vertical channels.
Each of these chakras has significant symbolic connotations,
including various human capabilities, subtle components (tanmatras), and seed
syllables (bijak sharas) derived from Sanskrit alphabet letters, thereby
covering all holy music.
The corporeal abodes of Shiva (consciousness) and Shakti
(power), the two divine principles through which the whole cosmos came into
existence, are located above and below these centers.
The intrinsic resemblance and interconnectedness of
macrocosm and microcosm, a crucial Hindu principle from the time of the
mystical scriptures known as the Upanishads, is therefore the basic premise
underpinning this concept of the subtle body.
The svadhishthana chakra is the second of the six chakras,
and it is generally listed from the bottom up.
It appears as a six-petaled lotus in the vaginal area.
Each petal has a seed phrase made up of letters from the
Sanskrit alphabet, in this instance the consonants "ba" through
"la."
The svadhishthana chakra is related with the human ability
for reproduction on a symbolic level.
It's also known as the body's seat for the delicate element
of water, the fluid medium that allows for reproduction.
