[653] "Born of seclusion" (vivekajaṃ): thought-conception (vitakka), discursive thought (vicāra), rapture (pīti), pleasure (sukha), and one-pointedness of mind (cittassa ekaggatā) — these are born, well born, produced, fully produced, and manifested in this seclusion (viveka); therefore it is called "born of seclusion."
