How to do spiritual things?

I'm learning a lot about spiritual things, enlightenment, altered states, etc. and I want to reach those things. So I know two things I'm going to do; Meditation and Yoga. But, is that all I have to do to live a spiritual life? What do people that you hear about in the Himalayas, and other places, that are trying to reach enlightenment do? I'm sorry if I'm unclear(to be honest, I'm not really sure about what I'm trying to do). But, thank you for helping!
