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?
not worrying about
the past and the future,
giving rise to the present moment,
becoming established in this place of full perfection.”
