Amrita Bindu Upanishad

 (The Supreme State) is neither to be thought of (as being something external

and pleasing to the mind), nor unworthy to be thought of (as something
unpleasant to the mind); nor is It to be thought of (as being of the form of sensepleasure), but to be thought of (as the essence of the ever-manifest, eternal,
supreme Bliss Itself); that Brahman which is free from all partiality is attained in
that state
