Khandha 5 is the support of suffering.

If we do not exist, there is no more support for suffering. Because what supports suffering is these five aggregates, briefly: form, feeling, perception, mental formations, and consciousness. Notice that suffering is not in the body; it's in the mind. If it sees the truth, the body is not us, the mind is not us, and suffering has no place to stand. Ultimately, it reaches serenity and joy. The more we let go of attachment within ourselves, the more comfortable and lighter we become. Proceed with meditation, at first it abandons the wrong view that the five aggregates are us. In the end, it sees the truth clearly, and it lets go of attachment to the five aggregates.
