From this videoconference talk from 17 May 2019, Ajahn Anan discusses Visakha Puja and The Four Noble Truths.

An excerpt: "This week we are approaching the commemoration of the Visakha Puja... And we know well that this is the day that the Buddha was born, became enlightened and entered parinibbana, or final enlightenment, on the full moon of the 6th lunar month. The Perfectly Awakened One was born as a Bodhisattva on the full moon of Visakha, with his parami, or spiritual perfections, completely full. And this would allow him to fulfil an aspiration to become enlightened as a Buddha in this very life. But to get to this day the Buddha needed to build the 10 paramis such as effort, endurance, sila, metta, wisdom, and so on, to the level where he was willing to sacrifice his own bodily parts, and even his own life for the purpose of becoming enlightened as a Buddha.

Can we see that the virtue of great compassion that the Buddha possessed is unlimited and unbounded?"
