For sometime you sit in lotus posture and concentrate on a Mantra. I will tell you today, how to do meditation. Please give attention and keep your one palm on another palm.
The right palm should be upside. Now close your eyes and keep your body fully straight.
You concentrate your mind only on Om mantra. Don’t think anything else and try again try to see the Om.
Firstly you imagine a white big background in front of you. On this background you see the Mantra Om. This Mantra has been originated from the Namokar Mantra. Om is the smallest form of the Namokar mantra. This is the original mantra and you can not convert it into English or in other language. Now you concentrate on saffron coloured Om written on the white background.
Although the external eyes are closed, yet the internal journey is going on. You have not to take sleep and have to stop your mind from going outside.
