Visions better than drugs haven’t come.
Intelligence exceeding genius hasn’t come.
Titanic strength hasn’t come.
Beauty to attract lovers hasn’t come.
Visitations from gods haven’t come.
Freedom from weariness hasn’t come.
An end to vexing annoyances hasn’t come.
Great wealth hasn’t come.
Fame hasn’t come.
Unlimited understanding of others hasn’t come.
Supernatural powers haven’t come.
The skill to spontaneously heal hasn’t come.
The gift of prophecy hasn’t come.
None of these things have come,
Yet I would not forsake this spiritual path.

All sorts of things are promised to you as a seeker of spirituality. Yet when these things don’t come, does that mean that you should forsake your path? Spirituality is not a transaction with the universe. It is an endeavor that we take up because it is our ultimate mode of being. If we get nothing for it, we should not be bothered. Who cares about powers? They only lead to temptation. Those who follow Tao should care only for inner understanding.
