The Secret to Understanding the Essence of the External World

“In our lives, there are five essential necessities, health, life, happiness, intellectual power and strength in the body. If these five aspects are not functioning efficiently, we cannot understand the purpose or essence of the external world…The time has come to look into the good and bad effects of these things and to eventually choose only what is good. This skill is available only with human beings, but not in other living beings. To obtain this skill, we have to possess the above mentioned five aspects. The secret to these five aspects is what we call Yoga.”
