Osho about :-ਸਿੱਖ ਗੁਰੂ ਅਤੇ ਗੁਰੂ ਗ੍ਰੰਥ ਸਾਹਿਬ ਜੀ सिख गुरु और गुरु ग्रंथ साहिब

The founder of Sikhism, Nanak, was one of those beautiful people for whom I have immense love. He was a simple man. He had just one disciple, and that too because he loved to sing. All his teachings were delivered in singing, spontaneous singing-not like a poet composing and his disciple would play on a simple instrument just to give some music to what the Master was saying

From Personality to Individuality, Chapter #11

Nanak attained God by singing to him, Nanak's quest is very unusual - his path was decorated with songs. The first thing to be realized is that. Nanak practiced no austerities or meditation or yoga, he only sang, and singing, he arrived. He sang with all his heart and soul, so much so that his singing became meditation, his singing became his purification and his yoga.

Whenever a person performs any act with all his heart and soul, that act becomes the path. Endless meditation, if halfhearted, will take you nowhere, whereas just singing a simple song with all your being merged in it, or dance a dance with the same total absorption and you will reach God. The question is not what you do, but how much of yourself you involved in the act

Nanak's path to supreme realization, to godliness is scattered with song and flowers. Whatever he has said was said in verse. His path was full of melody and soft, filled with the flavor of ambrosia

Nanak, the founder of Sikhism, his songs. He roamed around the known world of his day with a single follower, Mardana Mardana means manly the really brave. To be a follower one has to be brave. Nanak used to sing while Mardana played on his sitar, and that's how they roamed around the world spreading the fragrance of the ultimate. His songs are so beautiful, they bring tears to my eyes. Just because of his songs a new language was created. Because he wouldn't listen to any grammar, any rules of language, regulations, he created Punjabi just by his songs. It is a tremendously strong language, just like the sharp edge of a sword.

Books 1 Have Loved, Chapter #5

GURU GRANTHA has compiled the sayings of ten living masters, ten enlightened ones. I say that no other book can be compared to it. It is incomparable. Nanak says, "Ek omkar satnam only one thing is true, the name of the inexpressible. In the East we call it omkar, om-only that is true. The sound of the soundless... the silence that pervades after the sound has left ek omkar satnam

And he was more generous in his attitude, he allowed anyone who wanted, to be in his world Even Mohammedans entered it, Hindus entered it, all kinds of people from different religions became part of it.
