What is the best way to train a horse to accept the bit?

Lots of bending and softening of the jaw
Leg to hand!
If you mean to put a bit in for the first time; If you put the bridle on the horse and just leave him/her to chill in the stable and think about if for themselves. To start with just leave them for 10 mins and the go up to 20. After that I would begin to lunge them etc. This has always worked for me :)
