I am a openminded man , who follows no religion and really interested in these things like aatma spirit etc (if they exist).Answer this
In a recent pooja (pitra dosh) the astrologer asked me my ancestors name , i asked him something which he could not explain very clearly i knew he didnt know. names are randomly given to someone. if my name is x i could change it to y anytime , infinite no of times. how does the pooja process or "mechanism" know that my grandpa is mr. xyz as aatmas dont have aadhar card/id. fakeers have described it as nameless even formless. also how would it be sure that a particular mr xyz is my grandpa bcz names are very common . if he would have asked for blood or something it would be more logical right?? just enchanting some random mantra for mr x mr y wouldnt just make sense. It would only make sense that aatmas have memories of their previous birth and will come on enchanting my name . but then another question arises- what allows them to keep that memory , and after rebirth it suddenly fades away?
