Om Swami
Is there a simple daily practice to build gratitude, like during meals?
Eat in silence with gratitude
Even if it is not possible every day, once or twice a week you can quietly take each morsel with gratitude. Such a meal becomes a yajna (sacred offering) and a sattvic (pure) meal in itself.
At least once or twice a week, a person can quietly and peacefully take each morsel of food with gratitude.
