Buddhism and Hinduism both believe in a materialistic world full of desire as illusionary and in some cases, both adhere to the name “Maya” to coin that of the reality we live in, which is full of ignorance and distraction.
That's where they part, Hinduism believes in the doctrine of Brahman, or Ultimate Reality. This essentially is what the Divine Creator truly is, an all-encompassing, preceding, and ultimate source of everything, not unlike Buddhism's ontological approach to the Dharmakaya, or in terms of being: Adi-Budduha.
However, Buddhism believes in the doctrine of emptiness or
Śūnyatā. There are two ways of linking it:
- If we were to go with the Advaita Vedanta teaching then we can adhere to the doctrine that Brahman is Nirguna(without parts) which coincides with the ontological approach of the Dharmakaya especially from Mahayana Buddhism, that emptiness pervades all things and the ultimate true body gives rise to all phenomena and is the source of the dharma.
- However, there are some other parts. While Advaita Vedanta believes in a non-dual Parabrahman or God, this cannot be said for another teaching such as Dvita Vedanta belief of the Saguna Brahman(with parts) which in a way deters from a 0 rating due to having parts breaks the rule of divine immutability. The same can be said for the Dharmakaya or Adi-Budhha. In some Buddhism doesn't adhere to an ontological Reality, but rather a consciousness part of the mind that people can get eventually, as opposed to a level of reality that needs to break free from all conception. To add to that Adi-Budhha as primordial Buddha representing the sky and the cosmos being the very true essence of people can achieve is not a universal view. Rather, some beliefs deter that Adi-Buddha isn't primordial but rather the first Buddha to turn in the ages and not a transcendental being.
Either way, Hinduism and Buddhism share lots of similarities which is obvious since the former came first and most of Buddhism takes some sort of inspiration without the need for a Creator entity. Regardless, the Divine Creator can be seen as the Nirguna Brahman or Dharmakaya equivalent thus 0.
