Day 3: Today is Sunday. Many people like to kick start new habits at the beginning of a week. Perhaps you have not been able to "get into" mediation on Day 1 or 2. Well today, Sunday - the beginning of the week - is a great day to jump in and start!
The number 3 has all kinds of spiritual connotations (mind/body/spirit, etc.). It is also associated with growth and moving forward. I invite you to reflect on the growth that you have experienced and the areas in which you are moving forward.
