According to yoga philosophy, the whole material universe is made up of three qualities, referred to as sattva, rajas and tamas. Find yourself a comfortable seat and begin with a centering meditation before moving on to learn about the characteristics of the three gunas. Meditate on these subtle qualities, thinking about their various aspects and how they may shape and affect your life. Allow the gunas to help you see situations in a new way.
