True is the Master, True is His Name-speak it with infinite love.
People beg and pray, ""Give to us, give to us"", and the Great Giver gives His Gifts.

So what offering can we place before Him, by which we might see the Darbaar of His Court?
What words can we speak to evoke His Love?
In the Amrit Vaylaa, the ambrosial hours before dawn, chant the True Name, and contemplate His Glorious Greatness.
By the karma of past actions, the robe of this physical body is obtained. By His Grace, the Gate of Liberation is found.
O Nanak, know this well: the True One Himself is All. ||4||
