Hello All. This is what I got.
Ashwini mudra is anal contraction up and in a little bit. Some say it works on sva-adhisthana. I don’t know about that. I do know I can use it to make the vayu go up the spine. I have used it as a short cut, instead of patiently waiting for the vayu to go on it’s own ashwini can speed it up.
Vajrioli. Hmmm. I can’t really say what thats for. But if you can feel the vayu currents then you should be able to figure out what it does.
Mulabandha - In my opinion proper Mulabhanda makes a very specific “connection” between the apana vayu and samana vayu. When this connection is made between the two currents there is a major increase in the force.
In my opinion proper Mulabhanda or easy Mulabhanda uses very little muscular force. If your squeezing everything too much this is no good. All this squeezing is exhausting.
Lie down in shavasana. Relax everything for a while. Breath in and sigh out - subtly. As your breath out RELEASE. Breath out and release. With every breath out let everything go in a subtle sigh.
It will be hard to feel the vayu when you have muscular tension. The goal here is to feel the vayu vibrating in the current of the subtle body. You can’t feel it if there is muscular tension or your clinging to your squishy body. So recede awareness back into the subtle body by releasing gripping with the sigh out breath.
Now when you get on down to the subtle body and you can feel the vayu vibrating all around start trying to make the connection with mulabhanda. LIGHTLY!!! Maintain relxation. No anal contraction. No urogenital contraction. It’s up above the perineum a bit. If your sufficiently relaxed and in touch with the vayu circulating in the sublte body when you make the connection you will feel it instantly, in the form an amplification of the energy, and you will know exactly where it is. The two currents are linked and this action of linking amplifies the above currents. If you can’t feel the amplification your not doing it right. If its hard your not doing it right.
On Bhramacharya. To me this means moderation of activities. How can you practice when you overeat and your belly is stuffed? How can you practice when you overwork yourself and your energy levels are low? How can you practice when you make love all the time? For women this making love is fine. For men everytime they drop semen the body simply has to expend vitamins, minerals, fats, proteins, and carbs to make more. Which it will do almost instantly. Survival of the species is a number one function. Prana is not lost through loss of semen. And if it was all you would have to do is breath to get more. Vitality perhaps. But not prana.
In regards to Bindu. Bindu is not “really” semen.
I’d also like to think that observance of Bhramacharya means teaching.
