I thought maybe you came up with that independently, just testing. I’ll look for it but it might take some time because I don’t remember where it’s located.
The idea that the father resides at Buddhi sounds rather peculiar to me. Buddhi is associated with the intellect and the vijnanamayakosha. Above that is the level of atma and the anandamayakosha. That’s seems like a more appropriate place for the father to me, whereas I’d put the “Holy spirit” at the vijnanamayakosha.
First of all, I’d like to leave out the discussion of koshas, as they are not contained in the authoritative Samkhya texts, and to my way of thinking, they just add an unnecessary level of organization to 25 principles, and I’m not well versed in the terminology. You need to understand that there are two terms used to refer to the first evolute of the root prakriti: Mahat, which means ‘great’, and Buddhi. The difference is that Mahat refers to the macro level, where buddhi refers to the individual level. In the texts that discuss Isvara, he is said to ‘rise’ (reincarnate) from prakriti like someone who has dived into a pool of water. His ‘investment’ or body is Mahat. From Mahat springs Ahamkara. This is the exact relation of Father and Son in Christian theology. This interpretation is further supported by the fact that, in the Samkhya system, both the observable world and the instruments that observe arise from Ahamkara. This is consistent with the teaching of Christ as the creator. In my view, the equivalent of the Holy Spirit is vayu (prana), which is defined as the common modifications of the internal instruments.
One further point, the description of buddhi as intellect is not really very accurate. It’s often used in introductory texts for people with no prior knowledge. The real definition of buddhi is the power of discrimination or discernment, the ability to determine the nature of a thing. This is at the micro level. At the macro level, it is something a little different.
