Vedic Psychology, Where to Read More?

In the meditation guide, Dr K describes a model of the mind. Let me summarise it:

1. Experiences first enter the conscious mind, through the sense organs (indryas)
2. They have a certain emotional energy (manas) which keeps them in mind. This energy can be dissipated by properly engaging with the experience.
3. If the energy remains eventually the experience will be taken up into memory, the storehouse of the mind (citta).
4. These stored experiences (samskaras) sit until they are pulled back into consciousness as a memory/thought by one of two parts of the mind either the buddhi or the ahamkara 4a. The buddhi is purely analytical. If you’re experiencing something the buddhi will bring out connected memories. The buddhi may bring out thoughts for slighlty different reasons as well I’m not sure. 4b. The ahamkara, etymologically I-maker, tries to allieviate pain by categorising the pain as separate from us e.g. A tragedy on the news, will sometimes make kids cry because they don’t have fully developed ahamkara’s but your ahamkara might shield you by causing you to think “ah it’s sad that is happening to them” or “the people doing this are real bastards”. Alternatively if you’re worried about the sacrifices and pain of work you might say to yourself “I’ll do a phd/stay in academia forever”. The ahamkara is pretty bad at dissolving the manas, It’s mostly just about not engaging with the pain, but that does mean it is better at forming longer lasting patterns of thought/ identities, because it doesn’t drain the emotional energy of things as much. 5 Once they are back in the consciousness as a memory/ thought they may be dissolved or not. If they are not they will be put back in the citta and the cycle repeats.

I really like this model of the mind but I have some questions: What specific kind of engagement with a thought will make it be processed or not? Why? Can that be explained in terms of this model or does it have to be abstracted away and explained in terms of something else? How can this model account for the seeming fact that our thoughts are rendered in words whereas in the model thoughts are basically shadowy images of experiences we’ve had?

I’ve tried to find answers to these online but, although the Sanskrit terms are pretty widespread they are imo not understood in such a tight, coherent, well worked out model of the mind. I wondered if any of y’all wise people had suggestions for a book, ancient or modern, about this Vedic model of the mind?
