Buddhism regards death and rebirth as a cycle which continues endlessly until enlightenment is attained. At that point the essence of the person may enter state of Nirvana or egoless self. Some Buddhists feel the enlightened person may opt not to enter to Nirvana but return to the cycle of death and rebirth to instruct others in their progress towards enlightenment. The period between death and rebirth is not consistent in all Buddhist sects
