Much is contained within this ultimate guide to virtuous transformation, including the eightfold path of classical yoga (or ashtanga yoga), which suggests a program of ethical restraints or abstentions (yamas), lifestyle observances (niyamas), postures (asanas), breath control (pranayama), withdrawal of the senses (pratyahara), concentration (dharana), meditation (
dhyana), and absorption
into the Divine (samadhi).
