user11541: It is said that Nirvana is unconditional i.e there are no conditions for it to happen. If so then why is Nirvana not happening now? Is my wish or suitability a condition for it happen?

user6949: Let me answer with an analogy:
Suppose there is a small hill covering a much larger hill obscuring it from view. An energetic, skillful young woman climbs the hill (Stream Entry). She is happy about her achievement but suddenly realizes she has a lot more work left. She eventually climbs the larger hill and attains a magnificent view of the valley like never before. Her perspective of the surroundings has changed forever.
In this story, the larger hill was always there. But, she needed to create conditions to reach the summit.

user12123: Your question is like this sort of question,
Think about a kid which is just started school, and he asks about this kind a questions from the his own class mates,

What is Quantum Physics ?
What is Universe ?
What is General Relativity ?
Can you explain wave function ?
can you explain Schrodinger equation

i point out this questions cause even some collage students can not explain these for exact point, those who can will not explain it to those kids because there at another level far away from the kids. So for this example just think how can kid knows about all that things one may be willing to be lawyer, business men .etc and only one kid will be a scientist how will answer those questions soon he became one. Yet he also can not answer those questions, except he can say this book has this and that man said this, kind of answers. 
so i'm telling here is if some one is on the path to achieve something extraordinary and noble,without going along that path see for our self is better, rather ask someone from same level,and it is useless. Because they maybe also on the path to achieve it, so their knowledge about it will also unclear not the exact.
Only possible explanation for Nirvana is we can not explain it. By following eight noble path anyone can see what exactly Nirvana is.
Hope you could understand. 

user43: Nirvana is suchness (tathata). This is why Buddha is called Tathagata. Suchness is when you don't crave for anything to be different than it is now. So, regardless of how your situation changes, you take it "as it is", at every moment in time. This is why Nirvana is called "unconditional", because it does not depend on the circumstances moment-by-moment.
But first you have to reach that state when you don't crave for anything to be different than it is. If you still have craving/aversion then Nirvana is not happening.
It's really simple.

user10967: @ Dheeraj Verma, you are continuously try to conceptualize the Nibbana. your inner mentality is keep you driving to fulfill your desire to feel,see or experience the Nibbana.Isn't it? I had this issue earlier. it's like blacksmith build his own cage more stronger and stronger and become prisoner in his own cage ignorantly. You build strong concepts,ideologies and conditions ultimately you will end up with depression and misery. this is not the path. I have faced this harsh reality and just cross the line. Just observe the nature and try to realize. Just carefully refer the life of Buddha how he observe the nature and then slowly and gently try to realize. Nirvana here and now. Metta!  

user-1: 
If so then why is Nirvana not happening now? 

Nibbana is an existing reality. Its obscured by defilements just like a blue sky obscured by clouds. Insight-meditation and Jhana allows for the practitioner to experience and eventually attain Nibbana.

Is my wish or suitability a condition for it happen?

A wholesome intention is the start but not enough in and of itself. It must be followed up by practice. We ourselves must do the work, ie. working for purification of body, mind and conduct.
I highly recommend reading the article "Nibbana", by Ven. Bhikkhu Bodhi.
