Actually, part of idealism, Christianity, ancient Indian religions and other kinds of faith, all share certain common views with Buddhism, but that does not mean they are identical as a whole. Buddhism and idealism are fundamentally different despite their partial similarity. The differences are even greater from an overall perspective. Hence, to regard religion as idealism is purely an opinion of the West, with which Buddhism does not identify.

Our final goal is to produce a very strong and precise feeling of emptiness or impermanence each time we meditate. When not meditating, our temporary objective is to be able to experience emptiness and impermanence naturally without having to think specifically about these concepts in everyday life.

How to learn Buddhadharma is very important. If Buddhists don’t dedicate efforts to hear, contemplate and meditate the teachings, focusing instead on the rituals such as attending pujas, tsok, fire offering and empowerment ceremonies, burning expensive incense and worshiping the deities, among others, the real meaning of learning the Dharma would still be missing even if these are all done with great sincerity. Although a properly conducted empowerment is needed and useful, absent the practice of hearing, contemplation and meditation, the Buddha’s thought and teachings will not be propagated effectively. Holding concerns for personal health, longevity, money, work, family, etc. as their ultimate goal, Buddhist followers can neither benefit from practicing the Dharma nor actualize the path to liberation. And Buddhadharma ends up losing its real core value.

Bodhicitta is defined differently in tantra and sutra. Bodhicitta in sutra is the aspiration to attain buddhahood for the benefit of sentient beings through methods in sutra, but buddhahood is attained after three asamkhyeya kalpas.
