When your life is surrendered to Spirit the ego subsides. In that place you can trust your inner guidance.
If you’re not there yet, then follow your heart. Feel for the presence of expansion or contraction, and be attentive to not confuse emotion with true feelings of the heart. They are not the same.
If you can’t trust your heart, then look for messages from Spirit in the day-to-day activities of your life and in your dreams. What do the events in your life say to you?
In one form or another, Spirit will always guide a sincere devotee of Truth.
