Beyond?

Have you ever wondered, why we start crying when we are extremely happy and can't control our laughter; and when we go sad beyond help, we go "mad" and start laughing? I always, wondered what happens at the ends, the extremities, the pinnacles? Recently I listened to a song by Enigma, "I love you, I'll kill you." The part which caught my fancy the most were the following lines,

Look into the mirror of your soul
Love and hate are one in all
Sacrifice turns to revenge and believe me
You'll see the face who'll say:
I love you... I'll kill you...

Is it true? Can love when in its extremity, lose its identity and cause hate to grow. So, what really happens at the ends? Why is this confusion created? Why don't we act as is normally expected from a person? Is it a way to keep us away from something? Are we bound in some ways that even we don't understand? Can we let our passion grow only to a certain extent? People always said "passion knows no limits", and i wished it didn't. Chains in whatever form is suffocating. So, even if "He/She" says, not to go beyond, I would like to go there and see for myself, what lies there?

I think this is the "Maya" the philosophers have talked to us about for years. Beyond that, there is either everything, or nothing. Whatever that is, I want to experience it. To see beyond the boundaries, where love and hate, happiness and sadness, laughter and tears, everything meets and becomes one. To look beyond all of this. To reach where there is no confusion, where neither of these exist. To get freed from the chains.
