Dharma Wheel

Three brothers were in search of spiritual knowledge. On their way they noticed an old gate just in the middle of a field. And on the stone, pointing towards the gate, they could read a half-obliterated inscription stating: “For the deserving ones this gate will be opened.”
The elder brother just sat on the stone and concentrated upon the image of the gate. He decided that non-distraction would bring him to the goal. The middle brother explored the road leading to the gate and the field around it. He concluded that the understanding of place and circumstances is the most important.
The younger brother began to search for instructions. And, obeying the signs, he went to roam about, having lost even the memory of the gate. Once, walking on the road overgrown with grass, he opened the old gate, and being out he saw a toad, sitting on the stone and before him and a nightingale, studying him from the branch of a tree.
The two other brothers saw the rat, coming out from under the gate, and each of them said: The elder brother said: “This is the meaning of the flow of time;”
The middle brother said: “This is the entire mind, searching for attainment.”
Then, with the tears of joy in their eyes and having hugged and kissed each other, the three of them opened the gate so wide that a cart loaded with hay could easily pass through it.
