There is often a lot of rot talked about meditation and this or that method.
What Unis has said is true - keep it simple.
Just sitting quietly and calming the mind by observing your breath is ideal.

What you are going to do is to get to the point where you reach the stillness/emptiness within - which is the only place you can experience unity with the Oneness.

If you haven't done this before, you can find the mind tries to keep chattering on about anything, and it can be a bit frustrating trying to stop it. But if you give it attention, you give it power, so just let it be and observe it like a naughty child, eventually it will subside and the chatter will cease. With repitition you will eventually find that you can go into the emptiness, where there are no words - just knowing and being. Things you thought were important melt into nothing as you become One with the Universe.

Enjoy!
Love and light
