"Asking how many times one should chant the mantra is like asking how much water should be given to a plant for it to yield fruit. Watering is required, but the amount of water depends on the nature of the plant, the climate, the quality of the soil, and so on. Water alone is not enough. The plant needs sunlight, fertilizer, air and protection from pests as well. Similarly, on the spiritual path, chanting the mantra is just one facet. Good deeds, good thoughts, and satsang [association with virtuous people] are also necessary. When all of these are present, then one gets the benefit according to God's will." Mata Amritanandamayi Devi, "Amma".
