Knowing the Mind......
When you know that mind, when you see it for yourself, one of the results will be an insight that the mind is independent of this body. Independence means that when this body breaks up and dies, when it's cremated or when it's buried, or however it's destroyed after death, it will not affect the mind. You know this because you see the nature of the mind. That mind which you see will transcend bodily death. The first thing which you will see for yourself, the insight which is as clear as the nose on your face, is that there is something more to life than this physical body that we take to be me. Secondly you can recognise that that mind, essentially, is no different than that process of consciousness which is in all beings. Whether it's human beings or animals or even insects, of any gender, age or race, you see that that which is in common to all life is this mind, this consciousness, the source of doing.
Once you see that, you have much more respect for your fellow beings. Not just respect for your own race, your own tribe or your own religion, not just for human beings, but for all beings. It's a wonderfully high-minded idea. "May all beings be happy and well and may we respect all nations, all peoples, even all beings." However this is how you achieve that! You truly get compassion only when we see that others are fundamentally just as ourselves. If you think that a cow is completely different from you, that cows don't think like human beings, then it's easy to eat one. But can you eat your grandmother? She's too much like you. Can you eat an ant? Maybe you'd kill an ant because you think that ants aren't like you. But if you look carefully at ants, they are no different. In a forest monastery living out in the bush, close to nature, one of the things you become so convinced of is that animals have emotions and , especially, feel pain. You begin to recognise the personality of the animals, of the kookaburras, of the mice, the ants, and the spiders. Each one of those spiders has a mind just like you have. Once you see that you can understand the Buddha's compassion for all beings. You can also understand how rebirth can occur between all species - not just human beings to human beings, but animals to humans, humans to animals. You can understand also how the mind is the source of all this.
The mind can exist even without a body in the realms of ghosts and angels (what we call in Buddhism Devas). It becomes very clear to you how they exist, why they exist, what they are. These are insights and understandings which come from deep meditation. But more than that, when you know the nature of the mind then you know the nature of consciousness. You know the nature of stillness. You know the nature of life. You understand what makes this mind go round and round and round, what makes this mind seek rebirth. You understand the law of Kamma.
