Chanting and mantras: Fill your body with the power of your voice.
Chanting is one of the most effective ways to turn on without drugs. Chanting is a particular way of making sound with the human voice involving repetition of sound and tone. In some chants each syllable is held for an entire breath; in others a breath is taken only when needed. No matter which way you chant, the main idea is to develop your breathing through your chanting.
