Holy Avtar Vani - Shabad No. 249
Chaare ved paye yash gaavan ikko es akaali da;
Chhe shaashtar te geeta andar jikar hai ese khali da.
Guru granth vich mahima isdi vich kuran ehda parchar;
Vich anjeel vi rab de bajhon hor kise di nahin guftaar.
Sau syane te mat ikko bhed ehda koi pave na;
Kahe avtar bina gur poore gyaan es da aave na.
Meaning
No one can attain divine knowledge without the True Master. All the four Vedas worship this endless One; The six Shastras and the Geeta too mentioned about this massive void.The glory of this One is preserved in the Guru Granth and the holy Quran also seeks to address the same God. Even the holy word contained in the Bible relates to none other than (the same) God. Hundreds of wise men think alike still no one knows the divine secret.
