uddha Gotama was in search & practice the truth from all
aspects of knowledge from the most stringent ascetic practitioners
of the Hindu etc. All of these knowledges could not provide him the
answer beyong life & death that he is looking for. As such, he
sit under a Bodhi tree and realised the truth emptiness of all.
The 5 headed-snakes are six realms; heavenly beings; arahat;
Bodhisavattas and Buddha that having the same Bodhi (as that of
Buddha status surrounded by 5 headed-snakes). It is also
representing the samsaric defilement of 5 skandhas of Hindu then
(also representing sentient beings) that had been transformed into
Bodhi realised by Buddha Gotama. He then travelled around India to
liberate Hindu ascetic practitioners on emptiness and those aspired
to be free from uncompassionate self. A skillful way of Buddha
Gotama to assist the Hindu then by applying the culture of Hindu's
awe and worshipping the dieties to realise & actualize their
inherent Bodhi or in this regard, it is known as Lord Vishnu
Amitabha Buddha
