Duration: 24 hours a day, for 21 days
Visualize that you are light, that there is nothing else inside and outside. There is nobody, no world, there is only intense light. Visualize this from the moment you wake up until the moment you fall asleep, whatever you may be doing.
Slowly, after a few days, it will start penetrating even your sleep and dreaming states.
In dreaming also, you will remember yourself as light.
Even in deep sleep, you will remember yourself as light. You will be an eternal, shining light.
This technique is so powerful it will give you the clear experience that you will never die!
Light never dies. If you think you are matter, you will always have the fear you will cease to be one day. If you realize you are light, the fear of death will disappear!
