In plain words
One should give up the sense of separateness, 'Śiva is one and I am another', and always contemplate the non-dual: 'Who is Śiva, that indeed am I.'
Word for word
'Śiva another and I another': one should give up the notion of separateness; 'Who Śiva, he I indeed': thus one should always contemplate the non-dual.
