On with the text. We are here: PDF version: p.701 as printed in the pdf; a pdf reader will take you there if you tell it to go to page 748. On the 10000 Buddhas web page, search for "At that time, within the platform of light") From within the fireworks display of illuminated clouds, a voice commands Vajra Treasury Bodhisattva to explain the Ten Grounds in detail. V.T. Bodhisattva then lectures the assembly on how subtle, hard to speak of, hard to understand, hard to attain these teachings and practices are. Check your credentials, make sure you did your homework, this is advanced material, seems to be the message. He finishes off this particular passage (in verse) by re-stating his authorization to teach. The message here seems to one-up the previous warnings: don't even think of teaching this without proper authorization. He continues in prose, enumerating all the required qualities, for example "well-developed roots of goodness", having attended the Buddhas well, having a solid practice, having spiritual friends, having thought through the whole thing, and so on. He dwells a bit on how the intention to follow through with this training should be grounded in compassion. Then he finally starts to expound on the first ground: The Ground of Happiness/Joy. The qualities of Joy, Happiness, Calm, and freedom from anger are mentioned. This joy can be accessed by thinking of the Buddhas and other enlightened beings, the majesty of the teachings. We are at the end of PDF p.704. Next up: more on the Ground of Happiness.
