"Also, in the practice of kindness and generosity, a disciple should not be attached. Give for the sake of giving, not for the sake of appearances or for any merit you might receive in return. Be compassionate because being compassionate is good, not for some external reward. Why? Because practicing kindness and generosity without attachment is the way to reaching the Highest Perfect Wisdom, it is the way to becoming a Buddha."
"All that has a form is illusive and unreal. When you see that all forms are illusive and unreal, then you will begin to perceive your true Buddha nature. The truth is that the Buddha you should follow is your own Buddha nature, neither me nor anyone else."
One of the fundamental teachings of Buddhism is that our sense of individuality is delusional.
The Buddha taught that we aren't really individual beings in the way we tend to think. We are really just part of everything else, like how waves are part of the ocean. A wave can be described as an individual, but it really isn't separate from the rest of the ocean.
The Buddha taught that what we think of as our self is actually not an individual being, but a combination of things. He called these the five aggregates. they are:
physical form, consciousness, feelings, perceptions and mental habits.
If we are just a collection of things, like parts of a cart, then our self is less significant than we think it is. What are the implications of this?
Well, our feelings of greed and jealousy become insignificant if we aren't so focused on ourselves. THe world becomes a better place with less selfishness. Recognizing ourselves as part of a context rather than thinking we are some separate independent being can go a long way toward fixing many problems in the world.
Selfishness is a big problem. Because of selfishness we are greedy. Because of selfishness we are jealous of others and we tend to get upset if we don't have everything we think we deserve. Because of selfishness we take others for granted, which can greatly damage our relationships. Selfishness is at the root of most of our human problems. a lot of our anger is motivated by selfishness as well.
If we recognize others as ourselves then we are certainly less likely to harm them.
It can make us want to help them instead - and ultimately, helping others is really important in Buddhism. When we recognize that we are everything, it can be easy to forgive everything - or at least accept everything.
