Dear Timothy,
In the Commentary to the Buddhava.msa, transl as "Clarifier of the Sweet
Meaning" about the birth of Gotama the Buddha in Lumbini Grove (CH XXVI):
Queen Maya wanted to hold on to a branch and it bent down to her so that it
came within reach of her hand..
Mahaaparinibbaanasutta, The Bhagava's last place of rest, in the Salgrove of
the Mallas:
<At that time the twin Sal trees broke out in full bloom... And celestial
coral flowers and heavenly sandalwood powder from the sky rained down upon
the body of the Tathagata, and dropped and scattered and were strewn upon it
in worship of the Tathagata...> (Transl Wheel 67-69)
There are earthquakes at important moments, there is a passage about rain in
the Co to the Jewel Discourse, but this is quite a study. Do you have a
specific purpose with this?
Nina.
