These things r wrong especially... but I dont want to hurt u....
You are not hurting me my dear brother, we are all muslims and brothers, you are putting your understanding across which is absolutely fine.
NOw lets come to the points.
First of all let me assure you that I have been going to Mazar's for years and do not know a single person worshipping WaliAllahs there. Infact they go their and offer Namaz, Nawafil etc.. They try to devote themself to Allah and ask help of Allah with waseela/wasta of WaliAllahs, no one ever thinks that WaliAllah is Almighty God, every mature muslim understands Sorah -e- ikhlas (except Rehman MaliK) and no one ever thinks someone equal to God. so That's the internal bit of people go to Mazaars.
Now external bit.. Kissing graves, hands etc..
I kiss hands of my mother, grave of my father, grave of WaliAllahs with respect. how can someone decide that my gesture of kissing of grave is pooja ?
one, Who has got the power to see inside my heart and second, who gives authority to one to decide that kissing a grave is Biddah or shirk when they do not even know that what is inside my heart? Physical Gestures mean nothing without intention (Niyaat), even your real Sajda of Namaz is not acceptable if you do not intent from your heart that you are performing Sajda.
lso, when Angels did Sajda to Adam A.S why angels did not become Mushriks? The answer is because Allah Subhantaleh did not ask angels to accept Adam A.S as almighty GOd but said to angels that I made Human better than you so do Sajda-e-Taseem. Who gave that respect to Adam A.S? Yes, No one but Allah subhantaleh.. Same Allah gives respect to his friends WaliAllahs and a real momin will respect WaliAllahs as Allah wants him to respect his friends.
For arugment sake, If Sajda-e-Taseem did not make angels mushrik.. why it would make me mushrik if I do sajda-e-tazeem. Although I never ever thought of doing sajda to anyone except Allah subhanatelah..
So lets not decide on physical appearance and gestures!!!
May Allah Shows us right path iNsAllah and again you cannot see right path unless you follow people who were at right path.. "Ehdi nasiratal Mustakeema, Sirat AllahZeena, an amta Alemhim". IN my understandings people who were at right path are Hazoor Sheikh Abudl Qadir Jilani and his followers, such as Moeen uddin CHisti RA, Data Ganj Baksh, Baba Bulay Shah, Imam Bari Sarkar, Nizamuddin Auliya.. etc. THat is why I chose them to follow.
