Q: I read your answer to a previous question on this topic but am still not clear. What would be the state of all the knowledge of Advaita that I have acquired? E.g. I know now that I am not the doer and I should surrender the fruits of all my actions. But how can I still know this if I wake up with Alzheimer’s?

A: As I intimated in the answer to Q. 383, you have to differentiate between paramārtha and vyavahāra. In reality, there is only Brahman. There is only the appearance of people and world. They are mithyā. Their real substrate is Brahman.

We appear to have a body-mind and that body-mind is subject to disease, decay and death. This applies equally to the body-mind of the jñānī. The difference between the jñānī and the ajñānī is that the former knows that the body-mind is mithyā, while the latter doesn’t. Just as the body may suffer disease or even lose parts through accident, so the brain also is subject to illness and deterioration. Since the mind is associated with the brain, if the brain suffers loss, the mind will also. The memory may deteriorate or fail completely. This is the case irrespective of whether the jīva had previously gained Self-knowledge.
