For most of us, Rishi, they do not mean much or anything or perhaps were meant to be!
For me, personally, as a growing Jyotishi, growing in my awareness, they suddenly opened a portal! Like many others, then, now and perhaps even will in future (unless MAYAN MYTH does us all in and Mayapuri closes -- <<NOT!>>

), it was also a 'wake-up-call'!
I began studying it from the point of view of rectification of birthtimes, but though it gave some good hints and direction, the BEE (Bhramari) was leading me elsewhere! Including 'painting fences' and as I painted the fence, completely bored by the task and because it was imposed upon me, more awakenings arrived, along with the BEE who was not there to scare me but to give good news! I wrote the first words that some of you might have read bemusedly as "Chela Tales" as it was later called and I think first posted here -- with the horribly smelling wood stain on that fence!
Too mysterious, too poetical, perhaps too mystical? Reality can be ALL OF THOSE and MORE! No need to hunt and waste time in the 9th dimension or 99th one! MA is simple, Her love is simple and She loves her children. Afterall, it was SHE who gave us birth and keeps us alive, does SHE not?
Surrender is not WEAKNESS, it is about LETTING-GO!
AGING of the SOUL, I suppose...
Tantrik shastras teach that if we pay attention, on most days, the breathing can be noted to switch sides. Left nostril, right nostril and both alternate. Vaidic tradition has names for those! I will leave you with that thought! My bias has been that unless we get our attention captured, we do not explore and then we do not learn. We are like cats in that sense! If you have a pet cat, observe how she sleeps most of the day and wakes up only when its interests could get met! Then she circles its owner-parent and so on. MA knows how to handle the situation, while giving gifts of LOVE to the kitty, but never too many or the kitty will turn into a FAT CAT. Always, relying on ready-made meals, and treats and forgets that SHE was born to be a hunter and explorer!
Tattwa-Breath-Prana-Chi/QI are all related! A dead man never breathes! Making the most of one's breaths while one has those is important and our Duty to MA who suffered a lot to produce and deliver us ALL ...!
Love, Light, Gratitude, Shaz... (password that came out of an act of free-will beautifully synchronizing, for me, with FATE and MAYA!),
