In plain words
If you remove the barrier walls of attachment and Ahaṅkāra, the whole world is one!
In a while the whole world will flourish with one feeling, in peace and security. Then there will be no need to say ‘Lokāssamastā sukhino bhavantu’. The world will simply be happy. How? If we develop this feeling, the whole world will be happy. We should not wish only that our own Bhārata be happy. The whole world is one great mansion! In that great mansion Bhārata is one room. America is one room. China is one room. Pakistan is one room. Each of the countries is one room. Go to any five-star hotel and look: there are so many rooms. In this universe all the countries are so many rooms. But what makes them look separate? The walls in between are the reason for it. Knock the walls down. It will all be like one big hall. Those walls are attachment. Those walls are Ahaṅkāra. Knock down these walls of attachment and Ahaṅkāra. All is one!
I have become You, You have become me, (You and I together became the true teaching); when You and I together give the true teaching, honour and pride are no more; he becomes the perishable, he becomes the imperishable; when, joining perishable and imperishable, he knows the eternal, he becomes free of the mind, he becomes all; he falls under Māyā, he becomes Māyā himself; Māyā's twenty-five become mysteries; when he knows the mantra of Māyā's twenty-five, Māyā, Māyā, Māyā is then laid bare. O Rāma! O Sītā-Rāma!
