Can we do Vasi Yogam

Can we do Vasi Yogam for Longer Period

What is Vasi Yogam ?
In Pathanjali's Yoga Soothra -
Vasi yogam means inhaling the air by one side of the nose
and get back the air to another nose.
In this system your mind thinking that Moolaathaara Sakra is moving to upward.
It is absolutely imagination of our mind.
Moolaathaaram to aangjai all the stages are getting only by your mind's imagination.
In Vasi yogam your breathing system will be purified.
But you lose your life level. why because all our life level is attached with our breathing level.
Also waste your pranan.
In Tamil language Breathing Air is Prana Vaivu.
This air helps to life - live long time.
In Vasi yogam we lose our prana vaivu.

In Sithar maargam
they are also telling about Vasi Yogam.
But it is different from Pathanjali's Yoga System
They are telling that inhale the air by right side of the nose.
Push it to Head by slowly.
In our human body 9 holes are seems to be there.
but there is another hole is there in our body.
It is upside of the mouth.
This is the secret path.
That path is the way to send the prana Vaivu to head.
Then the prana vaivu not return back.
It is mingled with Pranan.
It helps your mind to inner conciuosness.
The mind not go around the outer conciuosness.
This makes very easy to meditate and way to feel or see sit pranan that is Athma.
Thanking you,
yours Brotherly Athman,
