A shocking news, and a big role to fulfil after what Rev. Chaiwat Moleechate has built and achieved in his reign. It is indeed sad to hear that a monk is responsible for the murder of another monk, what more IN the monastery.
Goes to show that with or without robes, our mind is what determines who we are. It doesnt matter if we are monks or nuns, or any other figure of worship. It doesn't matter if we have robes on or not. It is our minds that we have to control and tame, it is our minds that is independant of our body, and it is our minds that determins our motivation, our bodily actions, speech and controls our own minds. It is what will travel into our future lives.
Therefore, if the mind is unwell, even with robes on, cases such as this can happen. Any one can put on monk robes, take the vows and all, but if one's mind is not practising the correct path and following the correct path, it doesn't lead to anything eventually. Infact, it can be more destructive, breaking the vows of a monk.
