The underlying flowchart shows the sequence of pujas during the month of Diwali.
Dhanteras
Roop chaudas/ narak chaudas
Deepawali; Laxmi Puja
Bhai Dooj
Vishwakarma puja
The Laxmi puja on the day of Diwali involves the worship rituals to Mother Laxmi. But, Dhanteras puja is based on kuber dhana, which is not good. So, a proper justification says that Lord Dhanvantri, Guru of Health is worshipped, for we may foster with healthy mind. Healthy upper storey ensures peace in lower storey. Once we surrender ourselves at the Divine feet of Lord Rama, and do not take it back, then Lord Rama emerges form within. The houses and workplaces are cleaned during Diwali; this should involve cleaning our mind, for we may live with the Name at our lips.
We should spend the assets, lesser than our optimum limits, for the planet can be served.
