Many Headed Bodhisatvas in Ancient South East Asia

We up till now considered this group of figures from Ancient South East Asia. This is very exclusive. To be frank when I was near place in a bus in Bangkok due to traffic jam bus halted and was not moving for. Waiting few minutes I just got down and started walking about fifty feet I went one rural person was carrying one of the above idol of Bodhisattva.. and he wanted to sell it immediately. My curiosity arose and I bought that idol. It was the beginning of this group. So it seemed my duty given by God to work as much as possible on this subject. I have seen a figure even with four heads of this type. So number of heads differs and all that I am able to collect these many pieces in years so it is my duty to publish this knowledge. It is very unusual and important for Buddhism.
