In India they have the festival of lights. In the US we have Christmas lights.
There is something most fundamental about the psyche here… Lights in fall/winter… The inner light of life. Cultures have traditions rooted in the deepest fundamentals of life.
To feed the root of life, nurture, honor and cherish the roots of the culture. Keep it pure. Brush off any moss it may pick up from time to time.
Separate the wheat from the chaff, while understanding that divinity lies beyond the reach of secularity. Cultures (traditions) are here to culture humanity. Life is indeed subtle and delicate. Hold it so.
