People speak of knowing the Self, or Self-Realisation, but knowing the Self is just to Be the Self. To Be the Self is just Pure Being devoid of objective phenomena. In this there is no knowing or realising, just Being.
Here are some verses from Sr Ramana Maharshi’s Upadesa Saram (30 verses on the Essence of Spiritual Instruction):
25. Seeing oneself free of all attributes [objects]
Is to see the Lord,
For He shines ever as the pure Self.
26. To know the Self is but to be the Self,
For it is non-dual.
In such knowledge
One abides as that.
27. That is true knowledge which transcends
Both knowledge and ignorance,
For in pure knowledge
Is no object to be known.
28. Having known one’s nature one abides
As being with no beginning and no end
In unbroken consciousness and bliss.
