When the accountant Moggallāna asks if the Dhamma and Vinaya have a gradual training, gradual practice, and gradual progression like seen in many professions including his own, the Buddha describes a step-by-step training guideline starting with virtuous conduct all the way to dwelling in jhānas.

The Buddha shares vivid similes to illustrate the benefits of developing the recognition of impermanence. This practice gradually exhausts all passion for sensual pleasure, materiality, becoming, ignorance, and uproots the conceit ‘I am.’

The Buddha uses similes of a building with the peaked roof, fragrances, and regional kings to illustrate the importance of diligence in developing the Noble Eightfold Path.
