This is because when people who practice yoga say "consciousness," the meaning is different from the usual meaning of "consciousness" in everyday language. However, this is not done with malicious intent, but as yoga progresses, the range of conscious awareness expands, and the unconscious mind shrinks. While the unconscious mind remains in the sense of what one cannot consciously recognize, the range of consciousness expands, and therefore, the meaning of the word "consciousness" differs between the usual context and what a yogi means by "consciousness."

Therefore, a portion of what is considered the unconscious mind for ordinary people becomes the consciousness of a yogi, and even then, a part of the unconscious mind remains. However, this is a very advanced topic, so for the time being, it is acceptable to say that the unconscious mind for ordinary people is the consciousness for a yogi.

There are three classifications:
- Conscious awareness (for all people)
- The unconscious mind for ordinary people & the consciousness (conscious awareness) for yogis
- The unconscious mind (for all people)

However, even among yogis, the level of practice varies greatly, with some being very advanced and others not. Therefore, this classification may be more detailed or vary from person to person, but broadly speaking, this classification seems to apply.

In most cases, the unconscious mind for ordinary people refers to a state of extreme concentration, such as the "zone." This is a state of concentration for yogis, and this concentration is the basis for becoming one with the object. This is a basic state of meditation, but it is a very basic state. However, even this basic state is a special state for ordinary people that can greatly improve performance in sports, studies, and research, and it is very useful.

And then, there is a further step, a state of constant concentration. This is what is called "samadhi" or (the true meaning of) "meditation" (dhyana).

For ordinary people, this meditative state is a state of unconsciousness, but for yogis, it is a state of consciousness.

Within that range of consciousness, there is a distinction between the individual and the whole, but for the time being, it is often at the boundary of transcending the individual. Therefore, if one transcends individual consciousness, it becomes the unconsciousness in the general sense, and at the same time, it becomes the consciousness for a yogi.

Whether it's entering a "zone" or focusing on something, you become one with that activity. This is because, although it is physically "other," you feel a sense of unity at that moment, which is why it is recognized as a special state called a "zone." In the zone, it is a temporary sense of unity through concentration, but as it intensifies, you can constantly be in a state like the zone, and that is meditation. It's not just meditation; such consciousness constitutes the self, and it is also the key to self and other identity. Because that consciousness itself is everything, the seemingly contradictory logic that the unconscious is actually consciousness is actually true. This has always been the case, so for a limited individual consciousness, it may be a transformation, but for the vast consciousness that originally existed, there is no change. Connecting to such a vast consciousness is meditation.
