I have started reading
Seven Religions by Annie Besant, from transcripts of lectures she gave on the major religions of the world. Some of you may have seen a version published decades ago called
Four Religions. As the original series of lectures was for seven religions, the book has recently been re-released, with all of the lectues now included.
Hinduism is the first religion covered in the book. I have only read the frst few pages, but I must say, the philosophical basis of Hinduism is quite like Theosophy, although she says that the Hindu way to accelerate speed upon the Path is through Yoga. I am sure other differences will come up as I read further.
The book also covers Jainism, Zoroastrianism, and others, which I know nothing about. I am curious as to how all of these religions compare to each other.
