Drop the notion of separation, that you and the (Jeev)Atma and (Param)Atma are different. The Param lives in us and we live in it. This is what Agathiyar told us that he was the Prapanjam and that he lived in it and it in him. There is no distinction between these. But as creation is a play of Maya, we see them distinguished, and different, taking on several forms, names, nature and characteristics. Now it is defined by so many words in so many languages. So, which is right? As Agathiyar says intellect cannot point us to it. It has to be felt. The vibration that is God has to be imbibed and felt and experienced. Only he can pass it on. So, all our effort is to bring us to this state of realization. We need to prepare ourselves to connect and have these energies and its vibration traverse within or rather rise from within and traverse through us right till the core of our being. We then are one with him, it. The differences and separation then drop on its own accord.
