Because had there been a God like what we see in pictures, idols, movies, scriptures, religious books; it would have been easier for us to follow any path. As your guide would tell you that this way you can find the god. When you ask him ‘how will I come to know that this is God? The guide would say – he looks like this and all that stuff.
I can explain with a simple example. You will understand if you got this right.
To find God, a guide tells you to – ‘find a fruit in the forest which tastes like air, which smells like water, the touch of which feels like white, and which looks exactly like god.’ Even if you find that fruit, you wouldn’t be able to match it with what your guide has told you. Because the qualities expressed here are beyond the reach of five senses.
Path here does not mean the way or road or method or style or medium; but path here means preparation. And the only thing the preparation wants us to do is – to do nothing, end all the doings, stop acting, cease your existence as ‘I’ and be empty. Then only god will come down and fill in your empty space and you and god will be one.
