In every expedient presented in the Lotus Sutra, the expedient is also useful and a necessary step along the way to the ultimate teaching. Nothing the Sravakas or Pratyekabuddhas were taught was useless or of no value. Everything they were taught is necessary to their practice and to our practice even today. The Four Noble Truths, the Eightfold Path, the Twelve Link Chain of Causation are all important and necessary teachings to enable us to fully understand and practice the Lotus Sutra.
