The Masters in the line of Guru Nanak talk of Truth at many places in their writings. Ordinary people believe that it means that they should speak the truth which is an element of Sato Gun (good attributes) and is essential for spiritual progress. But the study of the Adi Granth, shows that the word 'Truth' has been used in it to denote Sat Punish (The True One – the True God).
Oh Nanak, consider the True One to be the Truth.
Sri Rag M1, 15-18
True is the Creator, True is the Cause, True is the Lord, True is the Master's support. Utter the Truth, For Truth brings enlightenment.

Just as the Immortal Lord is beyond the limits of time, similarly "Truth" has neither a beginning nor an end. It is expressly stated in the Jap Ji that:
True in the beginning, True through the ages. He is True. He shall ever be True.

Truth is therefore the name of the True Lord, the Creator Himself. The qualities attributed to Truth are the same as those attributed to God. The Gurus in line of Guru Nanak have also used the word Naam or Divine Melody for Truth.
For him who loves the Truth, True is the Word and the Melody. The Name of God dwells in his heart. He gives up anger and egotism.

He is freed from the snares of the Negative Power (Kal) and crosses the ocean of worldly existence and is honoured at the door of the Lord.
