Summary
This quote means that when we constantly chase temporary pleasures and indulge in excess, we are likely to encounter more disappointment and dissatisfaction than genuine fulfillment. The metaphorical image of diving to the bottom implies going to great depths in pursuit of pleasure, but instead of finding valuable treasures (represented by pearls), we only find insignificant and insignificant things (represented by gravel). It suggests that seeking deeper meaning and lasting happiness in life requires a different approach, focusing on more meaningful and lasting pursuits rather than temporary and superficial pleasures.
