Embracing the Mystery
I would agree that preparation for a ritual is necessary. I suspect that the necessary amount of preparation necessary for the ritual would be a function of the person's understanding and faith.
From what I understand, the southern California Buddhist community knew far, far in advance that he was coming. I imagine they could (and did) prepare for initiation rituals. There were quite a few Buddhist monks and nuns there.
However, the Dalai Lama did direct the non-Buddhists to think about these things in the terms of their own religion. (These ones would not be entering into the Buddhist community, but the sympathetic effect of thinking about the same thing in their own tradition could be a powerful boost to those undergoing the actual initiation.
That's what I was trying to get at. Non-Buddhists were not directed to become Buddhist or to undergo the Amitabha initiation, but rather to take the equivalent vow within their own religious tradition, if they felt so compelled. Furthermore, I imagine there was some preparation involved for those undergoing the initiation, as he explained that only those who had prepared sufficiently should visualize the Amitabha Buddha in themselves, while the other Buddhists should visualize the Amitabha Buddha at their crown.
From what I gathered, it was not so much that non-Buddhists participated in a Buddhist ritual. It was that non-Buddhists were offered alternatives that could make sense within their own religious tradition, but that expressed the same dedication to serve other beings through seeking enlightenment. This is why I thought the ritual was a good example of interfaith practice. People were practicing their religions together, alongside one another in a unity of love and compassion... but people were not practicing each other's religions. The ritual was interesting to me because it was uniquely positioned in a way that brought people together in spirituality while allowing people to retain their own traditions. There was no encouragement to convert, yet non-Buddhists were not ignored. Non-Buddhists were able to be participants rather than bystanders, yet in a way that encouraged them to be faithful within their own traditions.
