The following are verses from the Tip of the Writing Brush.
Looking all over the world and through all ages,
various paths of life exist also. 1-45
Over steep mountains, through tangles of thorns, along narrow ledges and
through brandished swords, if you come, 1-47
Yet a head a sea of flames, and a deep abyss,
you will arrive at a narrow path. 1-48
After following the narrow path step by step, you will come to a path.
This is the trustworthy main path. 1-49
Verse 1-45 is stating that each path of the mind leads to different outcomes, like suffering or joy. If you entertain evil, you will suffer. If you entertain good thoughts, you will have joy.
Verses 1-47 and 1-48 is stating that most people have taken the evil path (greed, arrogance, and self love). so they are reaping their end result of suffering. But if they continue forth to have faith in God despite their suffering, they will find the true path.
Verse 1-49 states that when they take the road to this true path (path without greed, arrogance, and self love), they will find the joyous life.
In summary, take the narrow path (path without greed, arrogance, and self love) to have a joyous life.
