How can infinite Absolute Knowers (Purusa) exist not limited by one another?

Q: If the number of Purushas (Atmas) be infinite they must be limited by one another. If a room is filled by ten articles of equal size then each article is one-tenth the size of the room, each being bounded in space by the others. The same must be the case with Purushas?

A: Had Purusha been a spatial object then it would have been so. The rule that when there are more objects than one, they are limited by one another (bahutve sasimatvam) is applicable only to objects occupying space and not to those that do not occupy space, such as mental images. If ten people standing side by side see an object, will everyone see one-tenth of it?
Thus the Purusha or Atma, being beyond space, though infinite in number does not become limited. Temporal objects exist with some variation in successive moments of time just as objects in space occupy it by their various parts. The thoughts of the mind exist in time and they limit one another by their sequence i.e. by the break of one thought and the appearance of the next after it. But the Absolute Knower being immutable is not a temporal object in the above sense (though said to exist from moment to moment). So it is without beginning and end. Hence the Atma which is only this Awareness is devoid of all sense of duality, immutable, infinite and innumerable… (from Samkhya Catechism by Swami Hariharananda Aranya)
