There's a lot of material in this ambitious work, translated with fidelity and compassion. It's heavy reading though - repetitive, dry (very idealist), abstract and disorganized (at least, my mind was disorganized after reading it - perhaps one of its unsaid objectives.) It was compiled at a time much like when it was written, i.e. when ideas were being thrashed out and the language still unsure of its place as a medium for such profound meaning. As a bridge from Tibetan to English for impatient westerners with a penetrating mind, or those just looking to pick up on any page to set the mind in a contemplative frame - dig right in. If you're interested in a more gradual exposition and are serious about understanding and remembering what you've read - I would suggest a more honed work of less profundity like Vairocana's five original transmissions or the Life of Vairotsana; or one where the doctrines are the topic of a thematic investigation such as van Schaik's Approaching the Great Perfection.
