Swadhisthan or Sacral  Chakra :  Swadhisthan Chakra is the 2nd chakra in our body and its situated at the level of sex organs or coccyx or tailbone in the  Lumber at the base of spinal cord . It is responsible for our source of creative power. Svadhisthana chakra is
associated with the reproductive and urinary systems in the physical body. Svadhisthana chkara is symbolized by a six petaled orange colored lotus. On each petal there is letter bam, bham, mam, yam, ram and lam.  When kundalini Shakti cross this chakra yogi attains the victory over the fear of water elements because water is the element of the swadhisthan chakra vam which is written in side the lotus. Yogi gets the complete control over his sex, anger, greed, attachments and proud etc. he gets the victory over his death, its Beej mantra is VAM. Svadhisthana is considered to be storehouse of all mental impressions and its counterpart in the brain is unconscious mind. When svadhisthana awakens, it presents many difficulties for the aspirant as whole of his unconscious material explodes in front of him. These karmas are beyond the range of analysis and they have practically no form but they constitute a great force. When kundalini is residing in Sacral chakra, all the negative and positive impressions of your unconscious mind express themselves. During this stage, you may be angry, afraid or full of sexual fantasies or you may also experience lethargy, dullness and depression. Sexual desires and fantasies can manifest in the aspirant at any stage of evolution but they are expressed very acutely and clearly when the kundalini is in Sacral Chakra. If aspirant understands the truth that desires can never be satisfied in one lifetime, not even in thousands of lifetimes, the kundalini can pass through sacral chakra relatively fast and will reach solar plexus chakra safely.
