Thank you, Ven. Dhammanando, for this explanation; this clarifies the issue for me. I'm always appreciative when you weigh in on questions here at DW. I'm still left with questions as to why the broader sense or use of jhana is not more prevalent in modern Theravada. It seems relegated to a "specialty practice," and in the west, it's been displaced to some degree by former Thai Bhikkhus who now teach insight/vipassana without much mention of jhana, if any at all. Of course, Ven. Thanissaro and others (Ven. Gunaratana, Ven. Bodhi, Ven. Brahm) teach it as a core course, but a cursory glance of many Buddhist seminars neglect it almost completely. My local (United States) Theravada temple makes only rare mention of it, and does not incorporate it into the teachings to the laity there.Dhammanando wrote: For this reason I think the rendering of "Jhāyatha, bhikkhave!" as "Bhikkhus, go do jhāna!" is apt to be tendentious and misleading, inasmuch as the noun jhāna will be likely to be construed in the narrower of the two senses when in fact it's the broader one that is more often intended.
Taken the way that Ven. Thanissaro uses it... "The word he uses for going to meditate is “to go do jhana”—jhayati is the verb in Pali. It’s a homonym with a verb for burning, as when a flame burns steadily. And the same verb is used for doing jhana. As you practice concentration, you try to make the mind burn steadily, with a clean, clear flame. Flames that flicker up and down are hard to read by, but a steady flame is one you can read by clearly. That’s the quality you’re trying to develop so that you can read the mind" ...the definition resonates nicely. I also have this sense that the piti and sukha that can be generated in jhana complements the eradication of attachment to the sense fetters that bind us to samsara. In other words, if we are working to free ourselves from these attachments to sensuality, why not integrate a practice daily that affords a supermundane form of pleasure? If western insight teachers are teaching detachment from sense fetters, why not teach jhana as an antidote?
