The most easiest thing one could do is to sleep for longer period. But, after that what happens.. One has to wake up from the sleep. The reason: the karmas of our past lives propel us to the waking stage. Can we declare that I'll go to sleep for three months. Not more than 8 hours you can lie on your bed.
There are three stages one has to pass through dreaming stage waking stage and deep sleep stage.
Once you are in a deep sleep stage you'll not realize whether you are alive or dead. After coming to waking stage then you'll say " that I had a nice sleep". Now, quesion yourself with that "I" used in your declaration. chant the mantra Who am I? something will dawn on you. This is called self-realization.
