There is a very fine line between preparation and attempt. While, IPC does not define either of them, it is very important to distinguish between them because attempt is a crime but preparation is not. Both, Preparation and Attempt are physical manifestations of the criminal intention. But attempt goes a lot father than preparation towards the actual happening of crime. While in Preparation, there is a possibility that the person may abandon his plan, but attempt leaves no room for that. For example, keeping a pistol in pocket and looking for the enemy to kill is a preparation because one can abandon the plan anytime, but taking out the piston and pulling the trigger is attempt because it leaves no room for turning back.
