as follows:
The semal tree is straight as an arrow; it is very tall, and very thick.
But those birds which visit it hopefully, depart disappointed.
Its fruits are tasteless, its flowers are nauseating, and its leaves are useless.
Sweetness and humility, O Nanak, are the essence of virtue and goodness.

When something is placed on the balancing scale and weighed, the side which descends is heavier.
The sinner, like the deer hunter, bows down twice as much.
But what can be achieved by bowing the head, when the heart is impure? (470)
