From the spiritual perspective, the purpose of life is to go through lessons and get experience. It is known that the body has a soul but it is the soul who uses the body to obtain physical experience and uses the body to achieve spiritual growth. The purpose of your life on Earth is not predetermined. You define the purpose of your life. You have a free choice and you can choose to serve the spirit in its desire to obtain the experience to help the spirit to grow.
Our individual spiritual growth is the main concern of our spiritual teachers. It is therefore a good idea for you to focus on your spiritual growth. It is your choice.
As you work on your meditations and your spiritual growth, it is your choice to invite your higher self into your body and to submit to guidance of the spirit. It doesn't relieve you from solving practical questions in physical life, but it takes the weight of responsibility for your life's' direction from your physical mind to your higher self.
As an agent to this work of the spirit on Earth, you become a messenger and a worker of the spirit on earth that can be called a 'lightworker.' It can be called an 'Avatar'. An Avatar is God incarnated on earth. As you connect to the spirit and become a worker of God, then you become an Avatar. It is your choice and it is an opportunity offered to you.
As you start performing the work for the cosmic intelligence on Earth, and as you commit to this work, you will be given more energy, more assignments and more help in completing these assignments. You'll still learn your spiritual and practical lessons, but in addition, you'll be plugged into the network of the lightworkers who do the work of the spirit and walk the path which is assigned by the higher spiritual intelligence.
The choice is yours and meditation is one of the greatest tools towards that path.
