Thought of the day
Today's Positive Thought:
Today's Positive Thought:Your inner wisdom is your greatest source of truth.Use it often.
Today's Positive Affirmation:I connect easily and often to my inner wisdom to getall the answers I need.
Today's Positive Visualization:I close my eyes and allow myself to connect to the Divinewithin. I affirm that within this inner presence are all theanswers I need. I allow the truth contained within to saturatemy being until I am filled with truth. I imagine myself goingthrough my day stopping often to connect to the Divine wisdomwithin me. I see myself using this inner wisdom in everythingI do. In my mind's eye I see myself making wise decisions andsharing this inner wisdom with others. I imagine myself experiencingthe confidence that comes from having access to the wisdom of theuniverse. I combine these images with the feelings of joy and letthem go, knowing that they will create the good things I amvisualizing and thinking.
