what is the meaning of samadhi? is the samadhi will be same on all yoga system? if not then what are the differences i.e. how many types of samadhi are there? how one can reach to samadhi level by chanting hare krishna mahamantra? what situation will become there? will there be difference between soul and supersoul during samadhi level or both will be one? many acharyas have many views about samadhi level which one is correct? please explain me clearly so that i will be free from this confusion.
