How to ordain and become a monk?

I want to devote my life to Buddhist way of meditation, I want to know more of Buddha teaching but my main interest is for go day and night actual meditation practices. I accidentally come across Sri S. N. Goyenka Vipassana retreats and attended one 10 day retreat at Dhamma Sota-New Delhi, after that from one year i'm practicing Vipassana meditation 2-4 hours daily at home. Now i'm very clear i want to devote my life for this.Its be very helpful if anyone can guide me into this.
