The Duality of the Nature and Nibbana

In our living world, when you closely observe you can see that all items / things / feelings are in pairs.

Let me explain you this further.
Long - Short
Black - White
Sad - Happy

When you think more, you will also observe that these pairs are interconnected in a way that these are dependent upon each other.

Lets say we say it is "long". Whenever we say that, we think of the "shortness" internally and we determine it's "longer" relative to the "shortness" picture we have.

Quite opposite happens when we say it is "short".

This implies that when we say one thing (long), it doesn't actually exist. It's just a relative projection of our mind. So the truth is this illusion. None other than that.

So the world we perceive is just a set of these ends ("antha"). Long /Short, Black / White , Happy / Sad etc..

Let's take it in another way.

We feel sad sometimes and it bothers us a lot. When you feel sad, internally we memorize a "happy" situation and relative to that we try to compare the current situation. And now are "sad". But where does that sadness "Antha" come from. It is from the happiness "Antha".

As I said those ends are just ends which do not exist. Hence a "paradox". So the wise person who sees these ends tries to be in the middle

Let me elaborate this
When you see the sadness, you should try to see the happiness at the same time and try to be in the "middle". Trivially, this will relieve you. Then you see the middle and if you try to attach to the "middle" you see that it is  also relative to those two ends. Ultimately you have to detach from that attachment to the "middle"

Hence there is no argument that this is "THE LIBERATION" one should achieve. This is the "Nibbana". The ultimate goal in Buddhism.

This is not a physical process. Hence

• You needn't give up materials which you consume
• You needn't meditate for hours. But you have to be conscious of your thoughts 
• You can be active as you were before 
• You can be more organized as you have no time to sorrow / compare and think further on those nonsense

The man who perceives this simple but delicate truth for a jiffy will always tries to be independent and will not see liberation through another being or power. He will be self contained. This is the feeling first step in the path to Nibbana. He has become "Sowan"
