If you chant it everyday, you need not chant any other Mantra. It protects you from calamities and confers upon you intelligence, learning and success.
Just chant The true sutra of the High King Sutra causing calamities to cease, merit to accumulate, to empower others and to promote living kindness. Highly recomended by the Living Buddha Lian-Sheng or Sheng-yen Lu (Padmakumara) for reciting.
