I might have misunderstood you. Apologies.

Seems we agree on a lot of things, but no. The Buddha taught reincarnation with His own mouth. It wasnt an added interpretation the unending cycle of birth death and rebirth with the only solution being cleaning your aatma of karma is the crux of His own life after he walked away from materialism.

Neither one, nor the other. Let go of clinging and the clumps of glue dissolve with it, no matter their content, no matter where they're located. No Lords, no Masters.

The only Master is your Soul imo. We can freely disagree here, obviously. But self control, self discipline, karmic cleansing and focusing on spiritual growth is the best one can hope for as a self aware human being.
