I believe so. I think it is the 1st dark night that spiritualizes a person. Part of it is a person transforming their views. For example, they may be irreligious and become religious. They may be violent and become nonviolent. They may be sexual and become antisexual. Or, on the contrary, they could be antisexual and become sexual.
The important thing is the whole psychology is affected. Everything is integrated into the new personality. Sometimes you will hear religious people say, "I died and was born again." You have to be careful with this. There are many deluded people in our time who like to parrot this saying. But, when it is true, this references how an old self with all its views, dysfunctions, and predilections passed away, and was buried in the ground. Then, a new self which was rightly oriented with reality was created in its place. This is an essential step in a mystic's development/maturation.
I think I may have to agree with you on this point, Alexander. For me, it was the death of my mother. The transformative period was the sum of years, however. Yet I bounced back and forth with the spiritual long before I could ever recognize the first Jhana. Another thing that hasnt been talked about on here, is the Kundalini awakening. For me, the first Jhana was not apparent until that moment.
Another interesting thing that hasnt been talked about much, is those of us out there in the world, that dont speak of thier experiences. My sister, for example. She found some charisms the first time she walked into a church, she said it smelled like roses. She has also described a fullness in the heart that expands outwards, much like that of the tactile sensations. (I think she may be describing the opening of the heart chakra, but im not entirely sure.) Yet there have been other women, that I have spoke with, that describe the same experiences. All have said that "It is my experience, and I dont share it with others." I thank them, of course, for sharing it with me. I would believe that these mentioned, have found stream entry, yet they are all very much immersed in the falsehoods of the christian church, very devotedly, I'd say. I say stream entry, because they do not carry any experience with them beyond the memory of them, see what Im sayin?
I also think it possible that others outside of the Buddhist community might not understand the meaning of a still mind. I am intimately familiar with the sets of feelings (Not all of the sensory charism), that correspond with the different stages of Jhana. I can say without a doubt, that I have progressed into the third Jhana without a still mind, not thoughtless. I've thought on it alot, how it was possible. It was actually just yesterday that I came to a conclusion, the thoughts, words, processes going on in those moments, were awareness. Jefferey posted it in the dependant origination thread and he described the 5 aggregates of clinging, along with awareness. Awareness being another of the cognitive function, although, I'll admit that it is "different" from the cognitive function. With awareness it has been more of a feeling, something is imprinted, inserted, separate, an outside influence. All the same, I've found it can also "drift", like the mind.
