I have noticed once when I was not paying too much attention to the breath
and it seems that I am doing reverse breathing.
I mean my belly goes out when I exhale and it goes in when I inhale.
and maybe that's why I am having this problem.
so, what do I do to correct this and breath normally
i.e. belly out when inhaling and in when exhaling.
I have been trying not too focus too much but I am just unable to do so,
and when I came to know of this reverse breathing of mine,
it's become even more difficult to not focus on it.
