[suhail Al ketbi]

Dose this practice  has limitations ?

I tried  but not work .

 

Do u have subject  that u feel it's  wild  open & u  can't  say  this doesn't  work or no useful.

There are plenty of things a tulpa can't do. A tulpa can't leave your body and interact independently with the world. A tulpa can't look to the left while you look to the right and see things you don't notice. A tulpa can't leave your mind and live in someone else's. What in particular were you trying to do that didn't work?
