One who dies in stubbornness will not be approved, even though he may wear religious robes and smear his entire body with ashes. Forgetting Naam, the Name of God, one regrets in the end. Believe in the Dear Lord and you will find peace of mind. Forgetting Naam, you shall have to endure the pain of death (Guru Granth Sahib Ji, 226).
One enshrines Naam within their hearts by God's Grace. Even beasts, ghosts and the stone-hearted are saved. The Naam is the panacea, the remedy to cure all ills. Singing the Glory of God is the embodiment of bliss and emancipation. It cannot be obtained by any religious rituals. O Nanak, he alone obtains it, who has it in his destiny (Guru Granth Sahib Ji, 274).
Search in the Vedas, the Puraanas and the Simritees; In the moon, the sun and the stars, He is the One. God's Word is spoken by everyone. He Himself is unwavering. He never dwindles. With absolute power, He plays His play. His value cannot be estimated; His virtues are invaluable. In all light is His Light. The Lord supports the weave of the fabric of the universe. Doubt is dispelled by Guru's grace. O Nanak, He then has unquestionable faith in Him (Guru Granth Sahib Ji, 294).
You keep your fasts to please Allah, while you murder other beings for pleasure. You look after your own interests, and so not see the interests of others. What good is your word? O Qazi, the One Lord is within you, but you do not think or contemplation on Him. You do not care for others, you are mad about religion, this is why your life is wasting away (Guru Granth Sahib Ji, 483).
Priest from both Hinduism and Islam got together and began discussing religion. A great fantasy has been created and no one could understand its mystery. They asked Guru Nanak to open and search in his scripture whether Hindu is greater or the Muslim. Guru replied that without good deeds both will have to weep and wail. Only by being a Hindu or a Muslim one cannot get accepted in the kingdom of God. As the color of safflower is impermanent and is washed away in water, likewise the colors of religiosity are also temporary (The Vaars of Bhai Gurdas Ji, 1).
