In the Mahapunnama Sutta - MK the buddha says;
"The four great elements, bhikkhu, are the cause and condition for the manifestation of the material form aggregate"
I cant work out how the elements are the cause for the material form, arent the four elements earth, fire, wind, water with, for example, earth just standing for skin, nail etc and so just characteristics of the material aggregate?
"And do you think that unto such as you, A maggot-minded, starved, fanatic crew, God gave a secret and denied it me! Well, well—what matters it? Believe that, too!
