Casually looking over the comments, I think some of us rely too much on semantics. A Muslim, Christian or Jew should be able to derive the same message even if they are not familiar with the terminology. If we continue to define this terminology based off of the Hindu denominations from which they derive, then we will continue to rely on their scriptures to understand our faith.
For me personally, closing off the 9 gates of the body means going beyond your 5 senses to paint your reality. God realization or Truth realization occurs when you go beyond the senses (sight, touch, taste, smell, hearing) and use the intellect to discern the objective truth of your existence.
This shabadh was posted earlier. It appears on page 656 of GGS.
When I read this, I personally derive a tongue in cheek reference in the second line. Kabir ji was not a yogi, yet he achieved what the yogis strove for. He stilled his windy mind.
The Guru has shown him the hole, alluding to the tenth gate. Not sure if Kabir ji is calling himself the guru, or alluding to God, i.e. with God's grace he has come to this realization.
The deer carefully steps through the hole. I assume the deer is another animal reference alluding to the mind.
He closed off the doors and the unstruck sound current resounds. He has learned to go beyond the senses to discern the truth about his existence.
He has spilled out the pitcher of the heart lotus. I think this is alluding to the droplets of water (soul/consciousness) being confined by the pitcher of the body. By spilling the pitcher, the droplets are re-united with the ocean (universal consciousness).
Now that he knows this (realized God/Truth) his mind is appeased.
