The Teacher, an inspired story

This story was given me about 5 years ago. An oldy but a goody to me.

One day an Angel was sent to stand by an aging master who had fallen asleep.
The Master awoke and rubbed his eyes, looked around.
Speaking to no one in particular he indignantly demands to know; "Where are all the children?! I was teaching and protecting them!"
The Angel replies "They are just there, up ahead of you, my Lord"
Well, what are they doing there?", he asks as he eyes the Angel up and down suspiciously.
"One came who had a soft melodic voice and they began walking alongside him"
"And just who are you?"
"I am the Angel sent to watch over you, my Lord"
"Me? Why would I need looking after?", he asked indignantly.
"You were having nightmares, my Lord. It was thought you might like company when you awoke from them".
"I am no child! I have children to look after and I'm going to get them"
The Angel nodded and moved aside as the Master marched forward, robes fluttering, reflecting his agitated state.
At the place where the path rose upward his foot sank and became stuck.
"Well, this path cannot be walked on! How did they get up there?" he demanded of the Angel.
"They simply walked, my Lord. It was their lightness of heart which made them light so that they did not sink".
"I am their teacher! I teach them how to walk!"
"Apparently, my Lord, they knew how to walk just fine on their own. They only but wanted someone who already knew the path to walk with them."
