Along with appreciating such stillness, it’s helpful in understanding and developing upekkhā to know that it’s an energized quality – it’s not a switching off or freezing of the heart. It’s a radical attunement to the experiential field, together with all its activity. The brahma vihāras are thus not just attitudes but are all qualities of energy, emotional energy as well, but emotional energy that is liberating, wholesome, noble and beautiful.
