In some cultures wedding dates, company incorporation dates, or official opening dates for a commercial endeavor get vetted astrologically to ensure the stars are in good alignment, and the date and time are auspicious and promise a bright future.
Regardless of whether you believe in astrology or not, setting the tone for an event or an endeavor, I believe, does make a difference. Sending out good energy, setting a clear direction in your mind for a new beginnings, or the tone for the New Year, matters because intent sends out forward energy.
We had a private book launching for my book DEEP LIVING and it was a very spirited event, I would even say auspicious. It's like when your New Year's Eve party is fabulous and it sets a festive and positive tone for the year. It's like when you give yourself a birthday bash and celebrate yourself and feel good about feeling good. It's like when you set the table for a special dinner nicely with effort and the intent to make it special. Set your mind up for success next time you create an event or start on a new endeavor.
