Buddhism speaks of Nirvana, which is the cessation of suffering. Nirvana means the cessation, the extinction, of all suffering. But our suffering comes from our wrong perceptions.
And that is why the practice of meditation, the practice of looking deeply, has the purpose of removing wrong perceptions from us. If we are able to remove our wrong perceptions, we will be able to be free from afflictions and sufferings that always arrive from wrong perceptions.
You have wrong perception on yourself and on the other. And the other has wrong perception on themselves and on you, and that is the cause of fear, of violence, of hatred.
That is why trying to remove wrong perceptions is the only way to peace, and that is why Nirvana is, first of all, the removal or wrong perceptions. And when you remove wrong perceptions, you remove the suffering.
To meditate deeply, you find out that even ideas like being and non-being, or birth and death, or coming and going, are wrong ideas.
If you can touch reality in depth, you realize that suchness, which means ultimate reality, is free from from birth, from dying, from coming, from going, from being, from non-being.
That is why Nirvana is first of all the removal of notions, of ideas, that serve the basis of misunderstanding and suffering.
The notion of death can not be applied to reality. There is a transformation. There is a continuation. But you can not say that there is death, because in your mind, to die means from something you suddenly become nothing.
From someone you suddenly become no one. And so the notion of death can not apply to reality, whether to a cloud or to a Human being.
The Buddha did not die. The Buddha only continued by his Dharma, and you can touch the Buddha in the here and the now.
And that is why ideas like being born, dying, coming and going, being and non-being, should be removed by the practice of looking deeply.
And when you can remove these notions, you are free and you have non-fear. And non-fear is the true foundation of great happiness. As so far fear is there in your heart, happiness can not be perfect.
And that is why Nirvana is not something that you get in the future. Nirvana is the capacity of removing the wrong notions, wrong perceptions, which is the practice of freedom.
Nirvana can be translated as freedom: freedom from views.
And in Buddhism, all views are wrong views. When you get in touch with reality, you no longer have views. You have wisdom. You have a direct encounter with reality, and that is no longer called views.
