the beauty of swadhisthaana chakra is immense. It is a very visual chakra, & those "visions" can be quite halucinogenic. The colours of everything in nature, around us, are intense, & there is a very good reason for this: we are moving towards the awakening of the pranic "body" sheath, the pranamaya kosha. We are starting to sense the energy all around, the energy growing within us, & the energy of others'. We are not quite at the awakening of the pranamaya kosha, but it is dawning.
We have to do something for this awakening to take place, & the main things to do are: keeping physically busy so that we can sleep well & keep our growing energy moving, & doing pranayama (breathing techniques) that are specific to kundalini experience. The 2 main pranayamas are bhastrika & nadi shodan, or, alternate nostril breath. The bhastrika fires up our energetic system, nadi shodan balances 2 of the main energy systems in our being: the energy flows known as ida & pingala. Ida relates to, but is not, the parasympathetic nervous system. It is a quiet mental energy. Pingala is a more dynamic, energy & relates to the sympathetic nervous system. Ida is more like consciousness whilst pingala is more like matter, & in kundalini yoga, these 2 need to be separated, & flow harmoniously, side by side. They flow up each side of the spine from mooladhara chakra, ida starts flowing to the left, pingala to the right. They then weave together across the spine at swadhisthaana chakra, separate to swop sides, & go up to the next chakra. This continues until they get to ajna chakra, inside the head.
Why are they so important? When they build up in potency, and flow harmoniously together, yet apart, a 3rd energy, the spiritual energy, the mighty kundalini can be stimulated quite effortlessly. It is a natural occurrence, & it resides in the most important flow channel (nadi), called sushumna. Sushumna relates to, but is not, the central nervous system in the centre of the spine & in the brain. The central nervous system is also part of the brain & the chakras are not only in the front & back of the body, but also in sushumna & the brain/mind complex.
Where the ida & pingala nadis intersect in the spine, where the chakras are, these can be stimulated with bandhas, or energy locks. There are 3 main bandhas & they are quite different from the bandhas of vinyasa & ashtanga yoga. There is a root lock, or contraction, of mooladhara chakra, an abdominal lift at manipura chakra, & a throat seal at vishuddhi, the throat chakra. They can be done separately; all together on holding the breath out (maha bandha); or root lock & throat lock together on an inhaled retention. As you can imagine, they greatly stimulate the chakras & when breath retention is done with the bandhas, they release an lot of energy.
At Swadhisthaana chakra, a lot of energy needs to be built up, & I shall explain why in the next post.
