The fact that the Dharma is not a single dogma, law, or fixed system, but instead an adaptable body of techniques available for any living being to aid in his development and liberation is emphasized by this metaphor. This wheel is said to turn by the current of energy from the needs and wishes of living beings, and its turning automatically converts negative energies (e.g., desire, hatred, and ignorance) to positive ones (e.g., detachment, love, and wisdom).
