I purify my body by chanting God's name.
I purify my vital by serving God.
I purify my mind by
emptying my mind for God.
I purify my heart by meditating on God's Compassion-Love.
A mantra is an incantation. It can be a syllable, a word, a few words or a sentence. When you repeat a mantra many times, it is called japa. A mantra represents a particular aspect of God, and each mantra has a special significance and inner power.
If you cannot enter into your deepest meditation because your mind is restless, this is an opportunity to utilise a mantra. You can repeat "Supreme" or Aum or "God" for a few minutes. Also, if you get an attack on the emotional vital plane and wrong thoughts or wrong vibrations are entering into you, you can repeat Aum or the name of the Supreme. In this case try to do it as fast as possible. When you are trying to cleanse your mind of impurities, you must chant as if you were running to catch a moving train. During regular japa, however, just say the mantra in a normal but soulful way. But do not prolong it too much; otherwise, you will not have time to chant the five hundred or six hundred times that may be necessary.
