"[Deepening is] the Bahá'í term for the process by which individuals deepen their knowledge and understanding of the Bahá'í Faith through study, discussion and meditation. Bahá'u'lláh bade his followers to 'immerse' themselves in 'the ocean' of his words so that they might discover 'the pearls of wisdom' that lay hidden in its depths. They should read his verses every morning and evening to uplift their souls; reflect and meditate on what they read; and strive to translate it into action. True understanding depends on purity of heart, and not acquired learning."

To Practice: Devote some time every day to listening to the deeper meanings of a sacred text.
