A 10th century spiritual work, Paramarthasara of Abhinavagupta is dedicated to monistic Shaivism.
Just as juice, jaggery and sugar are only different states of the same thing, namely sugarcane, so do all beings abide in the supreme Lord in different states or forms.
In the kindled light of the Self, stirred up by the wind of contemplation, the imaginations of the aspirant are sacrificed and he becomes one with that light.
The Supreme Lord seems still when the various elements are still, glad when they are glad, gloomy when they are gloomy, but truly he is not so.
When by virtue of the store of gems of supreme wisdom, collected in the treasure house of the mystic heart, the state of Maheshwara is reached; one realizes ‘I am in all. Hence, what misfortunes can befall, and by whom?’
