When ever Buddhism has taken root in a new land, there has been a certain variation in the style in which it is observed. The Buddha himself taught differently according to the place, the occasion and the situation of those who were listening to him.
Live contemplating the body. Contemplate internally and externally. Contemplate the origination of things in the body. Contemplate the dissolution of things in the body.
A virtuous man or woman who is determined to develop the Supreme Enlightened Mind, should thus develop it: I have to lead all living beings to put a stop to (reincarnation) and escape (suffering), and when they have been so led, not one of them in fact stops (reincarnating) or escapes suffering. Why? Because, if a Bodhisattva believes in the notion of an ego, a personality, or a living being, he is not a true Bodhisattva.
The world, indeed, is like a dream and the treasures of the world are an alluring mirage! Like the apparent distances in a picture, things have no reality in themselves, but they are like heat haze.
May all beings everywhere plagued with sufferings of body and mind quickly be freed from their illnesses. May those frightened cease to be afraid, and may those bound be free. May the powerless find power, and may people think of befriending each other. May those who find themselves in trackless, fearful wilderness- the children, the aged, the unprotected- be guarded by beneficent celestials, and may they swiftly attain Buddhahood.
Our problem mostly in our abuse of each other and the planet is greed. Just the rampant, incredible greed that people have partly because they're empty and they can't get enough because they're - you know, it's that Buddhist thing about the hungry ghost with the little mouth and the big belly.
Believe nothing, O monks, just because you have been told it, or it is commonly believed, or because it is traditional or because you yourselves have imagined it. Do not believe what your teacher tells you merely out of respect for the teacher. But whatsoever, after due examination and analysis, you find to be conducive to the good, the benefit, the welfare of all beings - that doctrine believe and cling to and take as your guide.
There is a way to be purified, to overcome sorrows and grief, to release suffering, to secure the right path to realize nirvana. This is to be mindful.
Giving up attachment to the world does not mean that you set yourself apart from it. Generating a desire for others to be happy increases your humanity. As you become less attached to the world, you become more humane. As the very purpose of spiritual practice is to help others, you must remain in society.
