Question: What physical sensations accompany attainment of the Creator?
Answer: There are no physical sensations in attaining the Creator since this attainment takes place at the next level of our perception. This is a sensation that shines on a person in reflected light. A person perceives it only in the quality of bestowal.
Question: But perhaps when attaining the Creator, does a person’s heart rate increase or does something change in the normal functioning of the body?
Answer: I did not measure my blood pressure or pulse, but it is quite possible that there are such external changes. However, a person does not pay attention to them; he is above physical sensations.
