In this fourth talk in a lecture series on the Great Disciples, the speaker, Ayya Santussika, tells the life story of two enlightened, fully ordained nuns. In fact, there were quite a few of enlightened, fully ordained nuns at the Buddha's time. The speaker also discusses how we can find the key to our own happiness in these nuns' stories, such as letting go, calming the mind, and realizing complete freedom from suffering. Finally, Ayya Santussika describes the Buddha's tremendous compassion for women. In his teachings, the Buddha acknowledged sufferings that were specific to women that are still relevant today.
