I feel a pillar of light extending from around my knees to a few meters above my head, overlapping with the front half of my body, and partially overlapping me, slightly in front of me.

It doesn't seem to completely overlap with me, but rather, it's recognized as a separate kind of light.

It's perceived as "light," and if one were to say that light is "seen," then that's what it is. However, it's not simply recognizing external light, but rather, it's not like the surrounding environment is brightly lit; it's more like "seeing a pillar of light existing."

Therefore, while the light might appear to be shining like ambient light or a spotlight when one reaches a state of tranquility during meditation, the light in this case is different. The key difference is that ambient light or spotlight-like light seems to stick to one's eyeballs, and the entire field of vision is recognized as light. In contrast, when one perceives "a pillar of light existing," the light is recognized not as a light that sticks to one's eyeballs, but as an object, like a three-dimensional object.

Therefore, it can be expressed as "seeing light" or "a pillar of light," but if interpreted literally, one might think, "Did the field of vision become brighter?" However, in this case, "seeing light" is more accurately described as "seeing a substance that is light."

It can also be expressed metaphorically as "seeing light," which means "seeing a mass or pillar that is enveloped in light." What that mass or pillar is depends on the interpretation, but it can be interpreted as a pillar of light, or it can be interpreted as something with consciousness.

If interpreted in a meditative sense, it's simply a pillar of light, but if interpreted spiritually, it can be interpreted as something with consciousness.

Even if it has consciousness, it's almost entirely lacking in conscious awareness. If there is any consciousness, it's simply "love" itself, and only the awareness of "love, nothing but love" exists within that pillar of light.

I feel that the pillar of light overlaps with the front half of my body and extends upwards.

That pillar of light, if expressed metaphorically, is like a child clinging to their mother's belly and simply feeling love.

That pillar of light might actually be the presence of my guide, and I feel that way. By overlapping with that pillar of light during meditation, I can deepen the realization of "love, only love."
