Are you talking permanently??
There are potentially two questions, the answers for which you should be seeking. Should you ever do inverted asanas ? If it is possible to do those asanas safely in the future, exactly when is it safe to resume ?
I strongly advise you to ask for guidance from your Guardian Demon regarding this matter. Even for normal yoga, resume only after you have received green light from your Guardian Demon.
Also, I wanted to address one more thing.
All the work I put into my soul goes down to the drain
The work that you put into your soul has not gone down to the drain. An accident has nothing to do with regressing the progress of the soul. Even now, at this very moment, the mantras that you may have vibrated before or the meditation that you may have done before may be affecting your soul positively albeit in a lesser magnitude. You may not realize this but it is not the accident that may have affected the progress on your soul negatively but it may be you yourself who may be doing the same by thinking in that pattern. This is self sabotaging subconscious programming. Stop thinking this way.
Start affirming to your mind that all the progress that you have done on your soul is still there for you to resume. Your soul will actually lose progress if you do not meditate for a certain period of time but it will never lose progress from an accident. That's my point. Safe recovery to you, Brother.
