alright, as I see on his blog – I guess he is a Christian.

I would agree with the 1st sentence of the Conclusion.

in the conclusion he mentioned it himself that “Buddha doesn’t believe in God”. it is true – there is practically no any concept of God (or Paramatma / Bhagavan in sanskrit). I would add – as neither there any concept of soul (atma or jiva in sanskrit).

so, strictly speaking, Buddhism technically is not a religion – similarly to Thaoism and as I recall Thaoism. at most it is a philosophy with purpose of improvement.
(I don’t want to go too much into details)

therefore I think these 3 can’t be properly compared as religions. may be only as “organised religions” (large institutions with certain structures and hierarchy mostly viewed as encompassing their congregation and to some extent expanding that congregation) – which is more like material term rather than spiritual.

as for comparison betwenn other 2. as I recall, according to Vedic tradition, religion with Krishna in the center (as a supreme God/ Bhagavan among many demigods / devas) has specific term “sanatana-dharma” whish means “eternal religion” (or some translate it even as “eternal inheritant quality/ activity of the spitit soul”). while other other religions are considered as “upa-dharma” or “temporary path” (also – lesser ?), both in the sense that such religions are relatively brief in time (well, say – if compared with the life time of a planet, what to say – universe) as well as in the sense that eternal soul follows such path only briefly or temprorarily on its too long jorney through the samsara circle. also, “upa-dharma” religions tend to provide quite a limited spiritual knowledge.

however the concept of God, soul and their relations is present, which I guess makes them more similar than with Buddhism. although Christianity has much less explanation about personal aspect of God.

anyway, I think it is quite a nice article.
(BTW Michael – the central them of Gita is usually misunderstood – it is not the “holy warfare” but love, devotion and surrendering to God and his will – which is more or less the same as Christ’s teachings are about – as in “let it be your will, not mine …” )
