आत्मनिष्ठ or आत्मपरक is that which we know with reference to our self. It is real to us because we experience it but it need not be real to others who may not share our experience. For example, I may feel love or anger but others may not know it until I express it through words or action in some form or the other. This expression of the formless subjective state through form makes the experience objective, that is to say, it is no more confined to me but can be seen and examined or measured and quantified (if one could) by others. This is what is वस्तुनिष्ठ or वस्तुपरक .
But as you can see it is an error to say that the subjective does not have a reality. All that we can say is that it is a reality personal to the person experiencing it. In fact all objective experience passes first through a subjective state before expressing and manifesting objectively. Therefore it has been said as well as affirmed by mystic experience that the world itself has a subjective reality even though we are aware of it only in its objective side. The subjective Reality is the Dream state whereas the objective is the outer waking state. But the Supreme Divine Reality is beyond both, Shushsupti, or the Brahman out of which all emerges. There is of course a last final state, Parabrahman or Turiya that is beyond everything and yet holds everything within Itself.
