i am to start with QM can someone tell me of a nice book to start with the basics and slowly get into the rigors of QM
You can read them in parallel, as needed. Bowman's emphasis is on explaining things that might trip up a beginner, whereas Griffiths is training you to be a quantum mechanic and covers a lot more technical material. Bowman covers the meaning of the quantum state, quantum postulates, operators, dirac notation, and lots more, in an attempt to eliminate some of the inevitable confusion. It's a concise book that you'll refer to often as you are puzzling your way through basic QM.

how do i read now i mean start with griffith and then read Bowman or the other way....
P.S: i am an absolute beginner(in QM)
I agree with Tom 100%. Use Griffiths as your main text; use Bowman as a supplement. (Don't get me wrong, Griffiths is also an excellent pedagogical text--but every little bit helps. I wish Griffiths was around when I needed it, too! )I would say use Griffiths as your primary source. Just jump right in to Chapter 1, and if you don't understand anything come to Physics Forums!
