1. Not all sankhara lead to dukkha.
– The Kusala-mula Paticca Samuppada” that leads to Nibbana starts with “kusala-mula paccaya sankhara“.
– So, there are sankhara that DO NOT lead to suffering. In fact, those above lead to stop suffering.
– Specifically, those “good sankhara” are “punnabhisankhara done with comprehension of Tilakkhana.”
2. Of course, suffering arises due to many types of sankhara. Those are apunnabhisankhara, anenjabhi sankhara, and punnabhisankhara (done without comprehension of Tilakkhana).
– Apunnabhisankhara lead to rebirths in the apayas.
– Anenjabhi sankhara (arupavacara jhana) lead to rebirths in arupavacara Brahma realms.
– Punnabhisankhara (done without comprehension of Tilakkhana) lead to rebirths in “other good realms” (human, deva realms, and rupavacara brahma realms.) Good, moral deeds lead to rebirths in the human and deva realms. Rupavacara jhana lead to rebirths in the rupavacara brahma realms.
– The last two (Anenjabhi sankhara and Punnabhisankhara) also DO NOT lead to the end of suffering.
