Concerning the video on my previous post. It's created based on Ksitigarbha Sutra. Most Mahayana Buddhists know about this Sutra. At least they have ever heard the name. Ksitigarbha Bodhisattva in Buddhism is the Bodhisattva who represents the Great Filial Piety.
The base foundation we should build from learning Mahayana Buddhism is the Filial Piety. That's the first lesson we should take. And also it's a natural thing to be filial to parents, right?
Ksitigarbha Sutra is also one of many Buddhist Sutras that every Buddhist recite at home or at the Buddhist temple. In the Sutra, we can know clearly the benefit of the Ksitigarbha Sutra. Here is an excerpt from the whole Sutra taken from Chapter 13 (last Chapter) of the Sutra.
The Buddha told Akasagarbha, "Listen attentively, listen attentively! For now I shall tell you about those benefits one by one. In future times, any good men or good women who should see Ksitigarbha's image and hear this Sutra and, furthermore, read and recite it, and who should also donate incense, flowers, drink, food, clothing and precious treasures as offerings, in addition to giving praise and making obeisance to Bodhisattva Ksitigarbha, will gain twenty eight kinds of benefits, namely:
