Okay this is like saying you believe in allah right? have you seen him prove it to me, You breath in oxygen right? can you see it but you feel it prove to me exists. If you have issues with authencity of it ask your sheikh or your scholar or sumthing. Like i said i always try things and like to see for myself and if i see or hear things or feel spiritually different than i believe it. I follow my heart and my heart tells me its fine. Like i do zikr i thought was nonsense at first your soul leaving the body and being in another place doing zikr and your heart doing zikr, what i did was try it for my self and experianced the benefits of zikr and happy that i did.
