In Gurbani at many places there is a mention of Akath Katha[ it would mean the story untold/unstated]. What is this and what is the meaning of this.Kindly have a look at the following line. I have colored the line under question. Regards.

Maaroo, Fifth Mehl:

The invaluable value cannot be obtained; in His Mercy, the Guru bestows it. ||1||Pause||

The Supreme Lord God is imperceptible and unfathomable; meeting the Holy Saint, I speak the Unspoken Speech.

The unstruck sound current of the Shabad vibrates and resounds in the Tenth Gate; the Ambrosial Naam trickles down there. ||2||

I lack nothing; the thirsty desires of my mind are satisfied. The inexhaustible treasure has entered into my being.

The boiling cauldron has cooled down; the Guru has blessed me with the cooling, soothing Naam, the Name of the Lord. ||1||Pause||

****************************

I have been told that 'waheguru' is the Naam for us. However, at many places there is mention of one being blessed with Naam.One of the example is above.

What is the meaning of the line and what is the meaning , specifically, of 'The guru has blessed me ...............name of lord.'

Kindly clarify.
