I thought to commence a thread on the teachings of Bhikkhu Buddhadasa.
To start, the salient theme of Buddhadasa's teachings was his emphasis upon nature. Buddhadasa held that Buddhism had the nature of a science and was not a philosophy. This is because Buddhism teaches about "real things, which brings real results".
Buddhadasa used the following fourfold framework for the Buddha-Dhamma:
1. Nature. All things are nature. This is as the Buddha taught regarding all things as elements or dhatu, including Nibbana. In Pali, the words for nature are dhammajati and sabhavadhamma, which are close in meaning to the Pali word for elements, namely, dhatu. To realise all things are nature is the same as realising all things are empty of self.
2. Law of nature or natural truth. Dhammaniyama, saccadhamma. All things follow the law of nature, whether physical, social, psychological, mental or spiritual. The teachings of the Buddha are the expounding of the laws of nature.
3. Duty according to the law of nature. If we wish to live free from suffering, we are required to live according to the laws of nature. This is called duty.
4. Result of doing duty according to the law of nature. These are dhamma fruits or pativedhadhamma. The fruits of course is peace, harmony & happiness.
To end, this is part one about the scientific teachings of Bhikkhu Buddhadasa. If we ask the question, what thing did Bhikkhu Buddhadasa most emphasise, we can answer, nature.
