Ajapa-japa
Japa mantra is an ancient spiritual practice, as old as the Upanishads. The best mantra to use is the guru mantra or your personal mantra given by the guru. With continuous repetition and awareness of the mantra first verbally then mentally, it becomes ajapa. The mantra repeats itself spontaneously from the heart without effort. There should be continuous awareness of every breath and the mantra. Ajapa is the perfection of japa.
THE SUPREME PONTIFF OF HINDUISM BHAGAWAN SRI NITHYANANDA PARAMASHIVAM says that to be able to establish oneself in ajapa japa, one has to practice and live in integrity. One has to be integrated in his words, thoughts and actions both to himself and to others. If one is not in integrity, ajapa japa will never happen. With integrity, any mantra you use will become your vak siddhi. You will simply radiate that mantra, the energy of that mantra invokes.
