‘Soch’ is the key to start everything in life. It is a belief. The search for understanding the ‘Soch’ leads to ‘Khoj’. The quench of ‘Khoj’ leads to ‘Moj’ i.e. infinite happiness paves the way when the individual passes through the hard way of ‘Soch’ and ‘Khoj’. After ‘Moj’ there comes a time when everything comes to an end. After ‘Soch’ dies, everything dies and ‘Sunyata’ becomes the last phase.
@bodhi_bimal says, “Sunyata is the last stage and it signifies disappearance of the Soch. This life cycle of ‘Soch’ to ‘Sunyata’ is a definition of the ever-evolving and infinite cycle of the being.”
