Is it possible to become a buddhist without a formal teacher? I was reading a particular question about conversion.

This particular answer discusses how one converts to become a buddhist: How does conversion work in Buddhism?


  First of all, there isn't one agreed upon definition about when you
  are truly a Buddhist. Some people say you are a Buddhist if you
  consider yourself to be one, others say you need at least several
  years training from an acknowledged Buddhist teacher.


Is it possible to become a buddhist without a formal teacher or formal teaching? If so, does one just learn from online experiences and research?
Pretty much so. Buddhism is a path of personal growth, so you do what you feel it's best for your own development.

It's not something that I recommend, but you can even be a Buddhist and break all the precepts. The only requirement is that you mindfully explore the consequences of your actions (i.e. their kamma). Then you have a chance to learn why you are following the precepts, i.e. not because someone commanded you but because you know by personal experience.

If personal experience tells you that you need a teacher, then go for it. If you do better by personal research, then go for it. Experiment while always being mindful. That can never fail you.
