At Wat Phra Dhammakaya, February 3rd of each year is known as the Great Master Day — an important and significant day commemorating the passing of the Great Master Phramongkolthepmuni (Sodh Candasaro), the re-discoverer of the Dhammakaya Knowledge; the passing of Master Nun Thongsook Samdaengpan, the first meditation teacher of Master Nun Chand Khonnokyoong; and the day Master Nun Chand Khonnokyoong was cremated.

All three Great Masters are like the brightness that guides us in leading wholesome lives. They are exemplary models of the pursuers of Perfections who showed us the correct way to accumulate merit and pursue Perfections. They taught us about the truth of life and the Law of Karma so that we can live in this world safely. Although everyone is born into this world to accumulate merit, pursue Perfections and attain Nibbana, these Great Masters did so much more. They aimed to eliminate the source of all defilements, vanquish Mara, and bring all living beings to the Utmost Dhamma. And with boundless compassion and unwavering minds, they were willing to spend as many lifetimes as it took to pursue Perfections and reach the Utmost Dhamma.
