So, how does the Law of Correspondence (ĐLTƯ) work? From the previous perspective on the mind and the Self, each realm corresponds to a specific frequency of vibration. When the Self vibrates at that same frequency, resonance occurs—and we align with that realm. Take a simple analogy: to talk to a friend, it’s not enough to just pick up the phone. You have to dial the right number, and you must dial it correctly. Or another example: we tend to get along more easily with people we work with—they wear the same uniform, join in the same organizational routines, and work toward similar goals.
However, does resonating with the frequency of a realm (let’s call that realization) necessarily lead to encountering actual entities in that realm (let’s call that attainment)? That’s a question I’m asking myself. If, at this stage, I’ve achieved a certain level of meditative success, then why haven’t I seen—clearly or specifically—any particular realm? Could it be that I still need more time? Or perhaps my mind hasn’t truly reached resonance? Or maybe my desire to see those realms isn’t strong enough? Because, while I do occasionally intend to visit somewhere—to “check it out,” so to speak—those intentions tend to be scattered, fleeting, and not very focused. Maybe it’s also due to my solitary nature: perhaps no friendly beings in those realms feel inclined to stop by and greet me 😅. I don’t know. Seeing other realms isn’t my purpose in meditating. In fact, I often feel it would be a waste of the precious daily practice time to pursue such things. And yet, these questions arise now and then—like soft ripples on the surface of the mind. They vanish… only to reappear later, drawing me into reflection ☹.
So what about those cases where someone suddenly finds themselves in a certain realm, without any deliberate volition? Anh Alpha once said he fell into a realm of suffering during practice, when his Desire Realm mind—preoccupied with worries, business, and mental noise—took over his Self. When that happened, the Self resonated with a suffering realm, and in he went. In such cases, what do we call that state of absorption? Is it worldly, wrong, or right concentration?
From the perspective I’ve discussed, the act of entering samādhi and the laws that govern what happens within samādhi are two distinct processes. Once we’ve crossed the invisible barrier created by the 3 spatial dimensions and 1 temporal dimension of this physical world, we enter an entirely different frame of reference—a spiritual coordinate system. In that space, the Law of Correspondence appears to be the fundamental operating law. (Whether there are other laws, I do not know.) Whatever frequency the Self vibrates at—that’s the realm or domain it will correspond to.[1] It is as simple as that.

Notes:
[1] Furthermore, because the realms are arranged in ascending order from low to high, beings in higher realms can perceive or understand those in lower ones—like how a student in Grade 3 must know the material from Grade 2. In addition, realms are also ordered from heaviness to lightness: lighter realms allow easier movement, more freedom to glide or travel. For example, a being in the Second Jhana can descend to visit the First Jhana, but not the other way around. The highest realm—that of Santi, Nibbāna, or Ultimate Stillness—is the one with the most refined, completely flat mental waveform, unmatched by any other. Now, let’s consider Heisenberg’s Uncertainty Principle (UP) proposed by the German physicist Werner Heisenberg. It states that we cannot simultaneously know both the precise location and momentum of a quantum particle. The more precisely we know one, the more uncertain we are about the other. If a particle behaves as a single pure wave, we can calculate its momentum precisely—but we can’t determine its position. If we use a superposition of multiple waveforms, the interference allows us to localize its position more accurately—but now we can’t clearly determine which waveform (and thus which momentum) it belongs to. Let’s try applying Heisenberg’s principle to the Self: Before or without practice, the Self is a superposition of many overlapping mental waveforms—various mental atoms, each vibrating at different frequencies. This means we can more or less tell where we are physically (i.e., within the physical realm), but psychologically or spiritually, our awareness is erratic—we’re joyful one moment, irritable the next; blissful, then sorrowful; light and free, then weighed down. As concentration deepens, heavier and faster-moving mental atoms are gradually eliminated. In these moments, the Self may sense its alignment with certain higher realms, and its psychological tone becomes more coherent and peaceful. When we reach complete one-pointedness—the mind becomes a single, totally still wave—the momentum of the Self becomes clear and effectively zero (momentum p=m*c, nghĩa là động lượng = khối lượng*vận tốc = 0*0), vị trí của nó sẽ là ở khắp mọi nơi, nhu nhuyễn, dàn trải (chỗ này chắc là hơi gượng ép vì nếu nói mình tác ý đi đâu cũng được khi ở trạng thái này, tức là mình cũng biết luôn vị trí của cái Tôi?!). https://www.youtube.com/watch?v=TQKELOE9eY4;
