For hundreds of years, people have been talking about an experience called nirvana, moksha, emancipation, self-realization, salvation, or liberation, without understanding it properly. Yogis call this experience samadhi. Although many people think that in samadhi or nirvana everything is completely finished, it is definitely not a process of quitting the world. Nothing finishes, only one level of experience ends, but then another begins.
