I suspect that shiva has nailed it.

Krsna says "from Me come memory and forgetfulness."

Mind, intelligence, and false ego are subtle material elements that are perceived from refined intelligence. The scientists use of empirical observations are useless in understanding these and other things beyond matter. Their limited methods can't perceive ghosts or psychic phenomenon, etc. Nor can they see the prescence of the Lord in the deities.

There are many attempts to acquire information these days in varied fields. Unfortunately, information is too often mistaken for knowledge. if your method or approach is not suitable for the object being studied, then it is irrational. A thermometer will not tell you the time.

Scientists are relentlessly engaged in pursuing the answers to your question and many others - including life itself.

However, if life and its concomitant symptoms are not grossly material, then a gross explanation is nothing but a bluff-which Prabhupada so expertly revealed.

I think you can pretty much categorize memory with love or honesty or fear or any other numerous emotions and feelings symptomatic of consciousnss and experience. It just is. And the field for understanding these things is spiritual and not material.

It's unlikely the material aspect will ever come in.I perceive your question to be similar in nature to one I once posed about the verses in Bg. 2.62 & 63:

While contemplating the objects of the senses, a person develops attachment for them, and from such attachment lust develops, and from lust anger arises.

From anger, complete delusion arises, and from delusion bewilderment of memory. When memory is bewildered, intelligence is lost, and when intelligence is lost one falls down again into the material pool.

I wanted to know why from lust anger "necessarily" arises (as in the verse). It seems to me the rest of the verses were self-evident, but that one correlation was ambiguous at best since it is the exact opposite of the enjoying propensity in the material world. So I wanted to know the "mechanics of it."

Basically, I got some attitudes from devotees who wondered if I was "all together" I think.

It was explained to me 3 or 4 times by different persons (because I kept asking) that everything belongs to Krsna and a thief cannot find peace or happiness in transgressing the property of others.

Over time, I have come to accept this as an explanation wholly consistent with the doctrines and processes of a religious, spiritual discipline and have given up on my methodology of more mundane proof.

Anyway, I just felt "motivated" to suddenly reveal my mind and what I see as a similar experience. I will be wholly surprised if you get the answers in the format you requested.

Humbly yours - ethos.
