One object, one knowing mind. If you recognize 2 objects at the same time, there are 2 knowing mind. If you know 3 objects, there are 3 knowing mind – different object, different mind; not only the same mind knowing many objects.
Many objects, many mind. Hearing consciousness and seeing consciousness are different; but you can experience at the same time.
If you don’t know what the mind is, then you cannot be aware of the mind.
[Yogi’s note: Each moment, a new mind and a new object arise; if you think that the object and mind are old, it’s just a thought, a concept, coming from a new thinking mind.]
