Several of my Objectivist comrades confess to positive learnings from Buddhism, but exempt the Lhasa school form endorsement.

That said, of all the major religions, Buddhism (largely and broadly) is perhaps the least incompatible with Objectivism, if we can place it second to Catholic Scholasticism as expounded by Cardinal Mercier.

Many Buddhists say that the Tibetan school is not Buddhism.
