In the second jhāna, the pīti is going to be more like rocking or swaying than vibratory in nature—more like what was described as “minor pīti” in the chapter on the first jhāna. The pīti should remain at this minor level as long as you don’t let the sukha get too strong. What you want is sukha that is moderately intense and a mind that is strongly unified around this experience of sukha—in other words, moderate happiness/joy, strong one-pointed focus.
