My most dear, most kind, most precious wish-fulfilling one,
Thank you very much for your kind letter.
Since you have three children, the most important education is, of course, Dharma, and the most important Dharma is the good heart—to not harm others and to cause happiness to others, especially pure happiness. Not samsaric happiness but pure happiness, the peerless happiness of full enlightenment.
This is achieved through Dharma education, bodhicitta education and bodhicitta practice. Then gradually [the children will learn] to live their life with bodhicitta, so they will always think about the kindness of others and they will always generate a good heart and the thought to benefit others.
While we are causing happiness and benefit for others, then our own wish for happiness comes by the way, without effort. Success comes by the way, and not only that, we are able to cause happiness more and more for others, for all other sentient beings. Not only to become free from samsara, but to bring other sentient beings to ultimate happiness, enlightenment.
With much love and prayers ...
