My very dear one,
You and others who were helping [the center] gained merit like the sky! You were practicing, meditating and teaching. The essence is karma, what brings happiness and what brings suffering. To remind others of that is great.
The other thing is compassion, benefiting all the sentient beings who want happiness and do not want suffering. This is the cause of merit, like the sky. If teachings on emptiness happened, then that is the very root of happiness for yourself and others.
It is very understandable [that the center closed]. Everyone is getting old, so you have to think of your own preparation for death. That is also for the benefit of sentient beings.
So thank you billions and billions, to you and all your friends who helped [the center]. Thanks for all your help to others.
