It would be helpful to introspect and try to feel the core purpose of your own life, the trunk of your particular tree. What motivates and energizes you? Look for themes that have been there since early childhood. As you meditate, try to feel the essential aspiration of your life.
Once you have a sense of your purpose, it is important to honor it and allow it to guide your major life choices. As long as you stay aligned to your core purpose, the forms in which it will be expressed will reveal themselves. Those who stray from their essential vibration never seem to feel settled in anything they do.
