No one can tell you what your purpose is. Only you have the answer to that question.
And the true answer lies deep within your heart. There you will discover what is true for you.
We all have a reason for being. We all have arrived on planet earth for a specific purpose.
The general answer to the question of: What is my purpose? is that you are a manifestation of the Creator, and as such, you are to express through the vessel you reside in the magnificence of the gifts and talents that have been bestowed upon you.
How do you recognize the gifts and talents that have been bestowed upon you?
You must align yourself with your divine self. Your divine self is that aspect of you that is One with The Creator. It is the part of you that is eternal, is immutable, is perfect, is truth, is knowing.
When you have aligned yourself with your divine self the answers will be crystal clear. The divine self is directly connected with your heart.
You will have transcended the lower vibrational atmosphere and entered into the heavenly realm. You will instantaneously have an experience in your body that will affirm that you have aligned with The Divine. You may experience tingling, or vibrating, or the most profound sense of peace, or a feeling of being bathed in love, or a warmth that is indescribable. You will know. It is unmistakable.
The divine self has only your best interest at heart. The divine self being one with all that is will only guide us to do things that not only benefit us but the entire planet.
