The term "Saptaatika Prakarana" signifies that when a being is about to be reborn, and the remaining time is less than an "Antarmuhurta" (a very short period), the process of "Trikarana Kriya" (threefold action) begins. After rebirth, the being attains "Upshama Samyaktv" (state of perfect knowledge) after a certain period of time. The "Jghanya Kala" (minimum time) for the 26 "Prakrutik Satasthan" (natural states of existence) is one "Samaya" (a unit of time).
The "Karm Granth" (text on karma) states that the "Utkrisht Kala" (maximum time) for the 24 "Pravrutik Satasthan" (states of existence due to karma) is 132 "Sagars" (a unit of time). However, the "Kshaya Prabhruta Chuni" (a commentary) mentions that the "Utkrisht Kala" for the same states is 132 "Sagars" plus a little more.
The explanation for this is given in the "Jayadhwala Tika" (a commentary) as follows: A being who has attained "Upshama Samyaktv" and has completed the "Bisayojana" (process of understanding the world) of "Ananta Anubandhi" (infinite karmic influences) remains in "Vedak Samyaktv" (state of perfect knowledge) for 66 "Sagars". Then, for the remaining "Antarmuhurta", the being remains in "Samyagmidhyahristi" (state of right faith). Finally, the being experiences "Mithyatva" (falsehood). Thus, the total time from the completion of "Bisayojana" of "Ananta Anubandhi" to the experience of "Mithyatva" is 132 "Sagars" plus a little more.
Both traditions agree that the "Jghanya Kala" for the 21 "Prakrutik Satasthan" is "Antarmuhurta" and the "Utkrisht Kala" is 33 "Sagars". The "Kshaya Prabhruta Chuni" states:
"Ekkaisaa Bihatti Kevachir Kalaado? Jahanen Antomuhutan, Upakassen Tettisan Sagarovamani Sadireyaani."
The "Jayadhwala" explains this "Utkrisht Kala" as follows: A "Samyagdristi" (person with perfect knowledge) who is a "Dev" (god) or a "Narak" (hell being) dies and is reborn as a human being with a lifespan of one "Purva Koti" (a unit of time). After eight years, the being experiences "Ant..."
