We have a purpose. Our purpose is sometimes referred to as our dharma. Dharma is the performing of tasks or living of the life according to the wishes of the soul. Everyone has a dharma to perform. We also have qualities which we need to develop as part of our evolutionary process and karmic patterns that we need to redeem.
Some people are very aware of their life purpose.
Many struggle to find it out. In order to evolve we need to align to our souls purpose. Sometimes people worry about finding their dharma. It is not always easy to know what our dharma is. The extent to which we know or don't know or dharma can be a karmic condition.
