After much practicing to control the mind, i have come across a sense of duality. here my soul(self) communicates constantly with the higher self. within the same body ,self and higher self seems to be communicating with each other , mostly at a time of offering prayers.. but when in meditation , higher self seems to take control of the mind, it seems now the higher self begins to communicate with the supreme self.. what is the mystery of these bright lights of different colors behind closed eyes? sound of silence makes the experience more intense. every single time it cannot be imagination of the mind. every new sound around me designs the next task. what exactly is my task on earth. apart from meditation everything seems to be materially contaminated. how to avoid material desires and identify what is not material at all?
