In plain words
Because the water of the Manas is in the vessel of the body, through some delusion or other you are able to see your own form in it. Well, shall we believe that it is true? It is not true. You cannot say it is not your reflection. It is not the reflection exactly. How so? Students must understand this well: you see your face in the water; your very face appears there, but it is merely reversed. left appears as right, and right as left. So how can it be true? Through your delusion you believe this to be your reflection. This body too is bound up with delusion. So if we want to recognise Divinity, we do not need the body. We do not need the Manas. But until we understand this rightly, we must nourish the body, the senses, the Manas and the Buddhi well. The body must be there. The senses must be there. The Manas must be there. But we must experience them along the right path. When we do not experience them along the right path in that way, when we do not set them on it, and set them on the wrong path instead, then we fall prey to many kinds of pain, sorrow and grief.
All these come about only through delusions. You are travelling in a train. Who is travelling? You yourselves. But when we look out of the windows of the carriages, the hills, the mounds and the trees seem to run past. The trees are not running. The hills are not running. We ourselves are the ones running. So, simply through the fickleness of our mind, we fail to recognise that everything is reflections of its own true form, and we take this for the changes of Prakṛti. When we go on inquiring well in this way, where did this unchanging Satya, "I, I", come from? Only after the "I" was born did all this creation come. There is no creation without the "I". Only after the "I" was born was creation born. We must inquire in this way. We do not ordinarily understand this Ātma-principle. But without the Ātma there is no world. Though all that is, is That alone, we are deluded into thinking there is something which is not. However much strength one has, however much wealth one heaps up, without this grace of the Ātma everything goes to waste. People believe that in every man there is a free will, a thing called freedom.
