We are here to realise this Self

Sri Swami Vishwananda: We are here to realise this Self, so that our body, our mind and our soul become one.
And, as long as you don’t realise that and think there is a difference between the Divine and you, without trying to make them one, there will be always a barrier.
And, in that way, you will have to come again and again and again to work only on this unity between the human and the Divine.
