1. Cleanliness is next to Godliness

    The temple and altar should always be very clean and decorated with flowers and incense. We shall touch the Deity altar and Deity in very clean condition, after taking bath and washing mouth nicely. Practice washing hands after eating and wash with soap and water after toilet. Cleanliness is next to Godliness, so this point should be very carefully observed, then you will advance very quickly to the perfectional stage of Krishna Consciousness.
