Context: It's a song by a Sufi Saint called Bulleh Shah, of his spiritual journey and realizations therein, along with the poets emotions on the subject. Meaning: You can be anywhere and still connect to god, going to a Mosque and reciting a prayer is of no use if the same is not done from the heart, with complete faith, to establish a true connection. There is no use cleaning and beautifying your body from outside, if there is malice and deceit within. If the heart doesn't nurture the picture of The One and Only, but all others, no amount of prayers can ever reach him. For, it is no use committing a sin and then praying, because only deeds matter. We are all trapped within our worldly devices and hence have no time to even thank Him. A saint chants to connect to his god from within. They are the songs of his soul, as he is desperate to be one with Him. For this life is impermanent and there is no use just living for selfish needs. His love alone can enlighten our path, because that light is not restricted to the mosques and homes...but is omnipresent.
