Recitation of Gurbani
One day the Sikhs asked the Guru whether those who read the Gurus' hymns without understanding them derived any spiritual advantage from it. The Guru gave no reply at the time, and next morning went hunting. En route, the Guru came across a broken pot which had held butter. The rays of the sun were melting the butter on the broken pot fragments. The Guru took one of these fragments in his hand and said, "Look my Sikhs, broken pot shards - when they are heated, the butter that adhered to them readily melts. As the grease adheres to the potshards, so to do the Gurus' hymns to the hearts of his Sikhs. At the hour of death the Gurus' instruction shall assuredly bear fruit. Whether understood or not, it has within it the seed of salvation. Perfume still clings to a broken vase." The meaning of the parable is that whoseoever daily reads the Gurus shabads shall assuredly obtain peace. And even though he may not fully understand them, God will undoubtedly assist him.

Guru Ram Das has said: "The Word is the Guru, and the Guru in the Word, and in the Word is the essence of ambrosia."
