A simple daily routine
After bathing, light a lamp at the home shrine, offer water and a flower, say a short prayer or the Gāyatrī mantra, and bow. That is a complete daily pūjā. Before meals, offer the food mentally to God and set aside a little for animals or birds.
On weekends or festivals you can add more: a fuller pūjā, a stotra, a short havan. Consistency matters more than length.
