Before one goes through the gate
One may not be aware there is a gate
One may think there is a gate to go through and look a long time for it without finding it
One may find it and it may not open
If it opens one may go through it
As one goes through it one sees the gate one went through was the Self that went through it
No one went through a gate
There was no gate to go through
No one ever found a gate
No one ever realized there was never a gate
Even so, the perception that there is no gate is a subjective perception
There is no way of knowing except to go through it
