In Buddhist Cosmology, according to the Nepalese tradition, Swayambhunath or the Self Existing Lord, also known as Adi Buddha has never left his heavenly abode. And neither the Five Buddhas of Eternal Meditation or Pancha Dhyani Buddha, as they are known to the Nepalese believers. However, except their names, the colour of their aura and the cardinal direction they face when represented in a temple, we know not much beyond.
The names and attributes of the Pancha Dhyani Buddha are: Akshobhya who faces East and whose aura is Blue; Amitabha who faces the cardinal direction of West and his aura is Red; Amoghasiddha who faces North and whose aura is Green; Bhairochana is placed at the centre and whose aura is White and Ratnasambhawa who faces South and whose aura is Golden.
Each of the Five Buddhas of Eternal Medition, by their own volition, caused their individual heir-apparent to be produced who are known as Bodhisattwa. Pseudo historians and uninitiated erroneously classify them as the Young Buddhas-to-be. They too are in heaven and we know not much beyond their names, which are Bajrapani begotten by Akshobhya, Padmapani begottn by Amitabha, Biswapani begotten by Amoghasiddha, Samantabhadra begotten by Bhairochana, and Ratnapani begotten by Ratnasambhawa.
It is significant to understand the Indonesians of the past must have been familiar with names and attributes of the Pancha Dhyani Buddha and that they were objects of veneration. The image above is from the Temple of Borobodur in Indonesia where the images of the Five Buddhas of Eternal Meditation as well as the scenes from the time and life of the Buddha are as meticulously carved on granite.
And, this is what that provides us with the proof that in the distant past the ancestors of South-East Asia and Nepal shared cognate relationship. As an additional evidence we can cite that the concept of the Dhayani Buddhas is totally unknown in neighbouring Hindu India.
