loremipsum said:How is that achieved?
Eastern spirituality speaks of attaining enlightenment. More fringe theoriest like Max Spiers and David Icke tell not to go into the white light where the tricksters will start scolding you to go back to pay your karmic debt.
You need to get rid of present & past bad karma as much as possible in each life to enter nirvana (no rebirth).
The tibetan book of the dead explains what to do in the intermediate spirtual realm after your death and before a potential rebirth.
It helps to have someone read it to you when you are dying or have just died.
