Mantra is a technique and it is not the goal. The goal is the deep state you get in. So when you have gone into the deep state, where even chanting of the mantra is an effort, you will think, ‘let me be in this state and stop chanting’. But the mind can be very tricky here. It might just be that it’s lazy and say, ‘I don’t want to chant it’; so you have to keep watch.
