In the early suttas, the Buddha’s teaching on not self is often read as a denial of a permanent self. I find it more careful to say the texts deny a fixed owner, controller, or separate self inside body, feeling, perception, formations, and consciousness.
In the Mahāhatthipadopama Sutta (MN 28), the Buddha examines the five aggregates as not belonging to a self. In the Anattalakkhaṇa Sutta (SN 22.59), he points to unsatisfactoriness in clinging to impermanent phenomena.
My question: when the Buddha says an aggregate is “not self,” is he mainly describing experience, making a logical point, or pointing to a practice of loosening ownership? I would like to hear replies that take different angles. Please link to suttas you think clarify the point.
