Illusion. Dialectics. Truth.
Only recently (at the age of 36) I learned that dialectics is a branch of philosophy, not linguistics. Not knowing this concept, I came to the same conclusions. Brief essence of dialectics: "unity and struggle of opposites." Brief essence of my conclusions: “dynamic balance of opposites, + - at a specific moment / period of time, and strictly 50/50 at infinity in time”. This is the very essence, basis, foundation of the Universe, Nirvana, Nothingness, Non-existence. Absolute balance, when all opposites are strictly 50/50 balanced. When 10 units of good and 10 units of bad at the same time are neither good nor bad, this is nothing.
At first glance, it is paradoxical, but this Nothing is the basis of the Universe. All other religions and Worldviews are shells (superstructures) of this foundation. In Nirvana (in Absolute Nothing) there is no Buddha, there is no one and nothing at all, it is impossible to be there - this is an ideal concept (concept) - completely (100%) corresponding to reality. Other worldviews (religions) appear and collapse on the foundation of dialectics - these are illusory temporary and necessary shells. The better they are balanced (closer to reality 50/50) - the more bland and tasteless they are, the less attractive. The more attractive a religion or worldview is - the more unstable it is - the less it corresponds to reality, and the more disappointment it will bring to its followers after the epiphany or collapse of this worldview.
The percentage of reality of the three world religions according to my rough estimate (100% - full compliance with reality). Buddhism - 90%, Christianity - 50%, Islam - 20%.
The less the correspondence to reality, the more problems and contradictions are generated by religion or worldview. It is also interesting that Buddhism arose 2500 years ago, Christianity 2000 years ago, Islam 1500 years ago. A clear tendency to distort (damage) religions over time, distancing them from the foundation (basis) of reality.
Suffering purifies - goes to the asset of karma. The pleasures spoil - they go into the passive of karma. The price of pleasure (joy) is suffering (sadness) equivalent to the pleasure received. In this case, one must take into account the intensity and non-simultaneity (the scattering of suffering and pleasures over time). It is also important to understand that suffering (sorrow) and pleasure (joy) are physical and mental (mental), they are interconnected and interdependent - interdependent. It would probably be nice to have a visual actual balance of karma like a bank account, but most likely this is impossible, and you have to feel this balance intuitively, due to external circumstances and internal factors.
