I would like to get some opinions of my interpretation of the Pali term ekaggata.
I have found a few Pali dictionaries which translate the term ekagga as 'tranquil', which got me thinking. Perhaps ekaggata means 'tranquility' or what we refer to as still mind.
Here's my reasoning: Whilst approaching the first jhana I definitely experience fluctuating moments of still mind. As the first jhana is met, I can certainly say that there is a degree of still mind, as vitakka and viccara are maintained. As I move over into the second, I feel as if the still mind already established is focused in on and becomes the main attraction, as V+V drop away. As far as I can see ekaggata is listed in each of the four jhanas. Perhaps what the Buddha was trying to say that still mind is a required factor in all jhanas and necessary for forward momentum, right from the first. This makes a lot of sense as I still cannot identify one-pointedness in my meditation. My overall interpretation of the first jhana looks like this.
Concentration = vitakka and viccara
Pleasant feeling = piti
Satisfaction = Sukha
Still mind = ekaggata
This would support the idea that second jhana is just the need to concentrate dropping away, leaving the remaining factors. Combining V+V to form concentration also supports the terms movement away from samadhi. When concentration is used in the suttas the Buddha actually means concentrating, not absorption. It feels to me that he felt the need to break faculty of concentration into two when talking about meditation for better results, thus we have V+V (he was a master of breaking things down, after all). Therefore ekaggata is not concentration or a form there of. It is the faculty of still mind experienced in each jhana.
Furthermore, lending to this idea; joy is the defining trait in the first jhana for which there is a corresponding factor, Sukha the defining trait of the third of which there is a corresponding factor, equanimity for the fourth. So, why if still mind is the defining trait of the second, still mind is not listed as a required factor in any of the Jhanas? I would argue that still mind is listed as a factor by the Buddha and that it is ekaggata.
Keen to know your thoughts.
PS: if this is gets debunked, I have two more theories for ekaggata, spawned from my ongoing dissatisfaction with the term one-pointedness.
