There is such a thing as jivitindriya and jivita in Pali buddhism. Bodhi translates jivitindriya as life-faculty. A Dutch pali translator translates jivita as vitality.
In Bodhi’s Comprehensive Manual of Abhdihamma jivitindriya as mental mental (cetasika) is described as something that vitalizes the associated mental states. It has the characteristics of maintaining the associates mental states, the function of making them occur, manifestation as the establishing of their presence, and the proximate cause is the mental states to be maintained.
Together with vedana, phassa, manasikara, cetana, an element of samadhi, sanna, in abhidhamma it seen as a mental factor that is present in any moment of awareness of something, or, in any vinnana moment.
The Dutch translator explains jivita as: the life of mental factors, which comes down to: it maintains there presence, their continuation.
I tend to: a kind of mental factor that works like a kind of animation of the vinnana and all its factors. It makes the experience perky, vibrant, vivacious, vigorously. I have seen this many times in myself. There is something that makes some experiences extremely perky and others not, or almost not.
Maybe this happens when you read a book and the mental images become very perky, vitalized and it is like this is all real. Maybe it can seen this way? That it, as it were, animates. I think great
demagogue and speekers are also able to give rise to this. It is like becoming enchanted. Hitler was also able to do this. When a situation vitalizes, i believe, it is also enchanting and it is perceived as very real.
Maybe something like this.
