That Jīva (soul), which is facing the Udaya (rise)
of the body-making and status-determining Karmas related with the next reincarnation. It means that after a minimum period of one Samaya and maximum period of one Antarmuhūrta (time-period between 2 Samayas (smallest time units) and 1 Samaya less 48 minutes)), the Jīva is destined to come under the Udaya of the body-making and status-determining Karma of the next reincarnation.
