On the third lunar day (tritiya), when the Sun and Moon are both exalted, it is Akshaya Tritiya; Akshaya meaning 'undiminished'. Anything begun today is full of the strength of our luminaries and given the most auspicious start.
So, if you have a project you have been working on, or something you would like to begin, then today is the day! Even if you do not have something to work with today, its good to start with an intention, perhaps a personal ritual to begin something important in your life.
What will you begin today?
