When a young Buddhist first time knocks at the door of a Buddhist monastery and asks to get ordained, he/she may think that this is the now! or never! moment of their life. It happened to me too.
At the time, I wasn't aware that there are thousands of good enough Buddhist monasteries in the world. If your first choice Lord Abbot doesn't like your face or gender or skin color or way of moving your hands when you talk, say "Thank you very much!" and move on to your second choice. There is always another monastery and another Lord Abbot.
Looking for gurus... sorry, abbots, seems like deciding what netbook to buy, but do we know which teacher is right for us?
Is the road from California to Nibbanam shorter than the road from Malaysia, Laos, Myanmar, Thailand, Taiwan...?
The farmer orphan turned village monastery abbot who doesn't speak English might teach you more (about sweeping the stains off your heart and the leaves off the monastery grounds) than the guy whose talks you can order on amazon. The Forest Tradition is great (like a great Teak tree in a great botanical garden). No name, no publications, no website monks and nuns are the great Teak trees in the forest.
Don't give up and don't get disheartened if your first choice Super Monastery has a waiting list. There is a small monastery on the other side of the river in Luang Prabang... or take the bus to Temoh...
And don't give up if you give up after six weeks; just start again! Some monks enter a monastery at 9 years (as novices) and stay until death, and some monks weave in and out of monasteries all their life. (Nuns generally seem to be less fickle.) You don't enter a monastery to get a good-looking CV; you want to get closer to (closer to what?) step by step for the benefit of all beings.
My admirable meditation teacher was from Section 5 of Wat Maha That in Bangkok, which is the Central Station of Thai Buddhism. It is still a good enough starting place to travel Bangkok-Nibbanam in economy.
For Buddhists, "Love is a Kind of Faith." Even more so is becoming a novice. You will meet the teacher you deserve without hunting him or her down; and if you don't deserve it, you can hunt all your life and will never see the tips of his or her ears, though he/she is living next door.
