In the midst of a busy life, it may feel superfluous to take time and contemplate the purpose of one's life. But doing so is important.
As Swami Rama, the great Himalayan Sage, said, "Human birth is not an accidental phenomenon; it has a purpose. A human being is born to accomplish a goal."
The goal Swami Rama was referring to is the goal of knowing the nature of one's own self.
We may have purposes along the way, but the ultimate goal for a human being is Self-realization.
The science of Yoga is to enable the accomplishment of this ultimate goal.
