Still in the same year as Rāhula's ordination, the Buddha taught his son the importance of telling the truth in a discourse known as the "Ambalatthika-Rāhulovāda Sutta". In this discourse, the Buddha taught and encouraged consistent self-reflection, to help let go of all evil actions that lead to harm to oneself and others, and to develop self-control and a moral life. He encouraged reflection before, during and after one's actions, and explained that lying makes the spiritual life void and empty, leading to many other evils.
