Mind doesn't arise depend on only object

In abihdhamma (chapter 1-5 for mind&mind factor, chapter 6 for matter&nibbāna, chapter 8 for paṭiccasamuppāda&paññatti):
1 moment can separate to 3 sub-moments: arising, standing, and vanishing (upāda, ṭhiti, bhaṅgha).
1 matter moment = 17 mind/mind factor moments.
Paṭiccasamuppāda = cycle system of matter, mind, and mind factor.
Nibbāna = the opposite side of paṭiccasamuppāda.
Paññatti = imagination of mind&mind factors about paṭiccasamuppāda or nibbāna (everything).

• So, paññatti has no 3 sub-moments, we can't count it's moment.
• I.E. you can imagine "I get wings to fly", but it doesn't mean you really get wings. If the wings never get 3 sub-moments, arising/standing/vanishing, it is just imagination, not truth. However, something is imagination bases on truth, such as bird's wings. Because wings are imagination as well, but they base on the matter, which can get 3 sub-moments. So, bird can fly.

The explanation

1. Most of jhāna object is paññatti. No one can count paññatti-object's moment, because it never arise/standing/vanish.
2. Another, some jhāna has mind or perception as object. But that object is the past, which already vanished. Mind can know the present object as the present while it is taking a present moment (still in arising, standing, or vanishing state). but for the past or future object, mind can know it as it is unlimited. Similitude as we can see the present passing through car just the moment it is in our vision. But we can think of that passed/coming car, which being out of vision, unlimited.

By both case above, although the object is not present, the mind still can know it.
If mind have to arise depend on only object, we must know everything even when we are sleeping.
