On May 22, 2019 at 5:32 am, I briefly commented on what is meant by sakkāya ditthi, and promised to explain it in more detail.
Update on September 24, 2023: I think there is a better way to explain the anicca nature of this world. That is what someone needs to understand to become a Sotapanna by removing sakkaya ditthi. See “Anicca Nature- Chasing Worldly Pleasures Is Pointless.”
Recently published post: “Yamaka Sutta (SN 22.85) – Arahanthood Is Not Annihilation but End of Suffering” also discusses this basic point that there is no everlasting “attā” that attains Nibbāna”.
– Rather attaining Nibbāna means just stopping any future suffering for a given lifestream.
P.S. A few more posts will be published on this topic. I will add them here as they are published in this section:
“Anicca, Dukkha, Anatta“.
– The last two posts are under the subsection: “Sotapanna Stage and Tilakkhana” there.
