I've been reading a lot about Buddhism in the past days. It's one of the major world religions I've so far not known much about.
I've been reading in two introduction works, "Buddhismus" by Hans Wolfgang Schumann which is more popular, and "Einführung in den Buddhismus" (="Introduction to Buddhism") by Michael von Brück, which is more of an academic work. To find a Baha'i approach, I consulted "Buddhism and the Baha'i Faith" by Moojan Momen.
And I read some translations of Buddhist scriptures, mainly from the Pali Canon, from the Pitaka of teachings, mostly German translations by Karl Eugen Neumann. And "Udanavarga", a Tibetan text that isn't part of the Pali Canon, but shows some similarities to the "Dhammapada", translated by Michael Hahn.
So far, it has been most enlightening. I imagine that Buddhism is more easily accessible for Western atheists than, say, the monotheist religions, because you can as well see Buddhism as just a philosophy -- if you leave aside all the metaphysical embellishments around the core teachings. The practize of meditation has even been scientifically proven to work, so supporters of Buddhism never get tired of emphasizing how Buddhist teachings are absolutely compatible with modern science.
As I've mostly focused on the core teachings of the perhaps oldest Buddhist school, Theravada, which -- perhaps -- contains the most original teachings and least later additions and influences from other sources (compared to Eastern Vajnarana, Tantrism and Mahayana), I'm indeed surprised how thoroughly rational, intellectually challenging and coherent the teachings are (as far as I've been able to comprehend them so far), so much it makes sense to look at it as a scientific attempt to categorize and lay out a theory about the inner workings of human perception.
For me personally, it's also an intellectual challenge to bring Buddhist teachings in coherence with Baha'i teachings, to increase spiritual growth (hopefully ): Although the Baha'i religion stands in the tradition of Abrahamitic monotheism (Judaism, Christianity, Islam) and uses many similar terms and concepts, the Baha'i teachings explicitly acknowledge Buddha as a "Manifestation of God" alongside Moses, Jesus, Mohammed and Baha'u'llah; in fact, you cannot embrace the Baha'i Faith, without at the same time accepting the authority of the other Manifestations, including Buddha.
But how do you reconcile a faith/philosophy, that explicitly denies the existence of a soul, refuses to make statements about God and has a particular idea about reincarnation (though not of the self or soul, but of certain attributes) with monotheist conceptions? However, if you believe in Baha'u'llah's teachings and Baha'i theology, you have to.
I've got quite a few ideas about that, and insights which have been most enlightening to me, but I assume nobody here is particularly interested in them, so I won't bother writing them all down. (If you're curious, just ask!)
Just so much: A major teaching in the Baha'i Faith is about the importance of detachment from material, worldly matters on the path of salvation; Buddhism obviously is much more detailed on the "how" of achieving that, which is of huge benefit for my Baha'i interests. Also, the practize of meditation (I've started meditating a week ago, mostly mindfulness exercizes inspired by Buddhism), which is explicitly demanded in the Baha'i Faith, has yielded interesting effects on me already.
