Not Clinging to Pleasant States
We like pleasant meditative states. There's no problem with the pleasantness of them; it's part of our life experience. The problem is that we often devote our life energy to the getting, sustaining, accumulation, and repeating of these pleasant experiences. But, as we all know, these pleasant experiences don't last, so they don't really have the capacity to bring us happiness, to bring us completion, to bring us fulfillment. We're always seeking more—that's samsara, the endless wheel of becoming, fueled by wanting.
