The pīti, being the physical release of pleasant, exhilarating energy, could be anywhere from mild to quite intense. It can be finger-in-the-electrical-socket intense; it can be so intense that it’s not even pleasurable. And hopefully the pīti is accompanied by sukha, which is an emotional state of joy, happiness. Both pīti and sukha are required in order for the experience to be classified as the first jhāna. And most likely, the experience brings a big grin to your face.
