I find this a bit concise but I am a Buddhist living overseas without constant reminder of the Buddha Teaching. What I have heard is that: "สติปัฏฐานสี่ คือ กาย, เวทนา, จิต และ ธรรม "

Again, I think "kaaya" equates to siila, vedana equates thinking/a mental activity, citta is 'experiencing' and dhamma is 'human' reality. So you see, more explanations or discussions seem needed to share our view of this topic.

Please give us more simple explanations.
