A mantra is a syllable, a word or a sequence of words with a high spiritual vibration. The GURU MANTRA represents the essence of prayer, and anchors us in God, the Atma and the Supreme Self. It is the first initiation given by the spiritual master to the disciple.  The Mantra is like a “living” word…like a seed that grows into a strong tree, blossoms and produces multitudes of fruit.

 It contains an immense power for enrichment within itself – though only if the disciple always carries it in the mind and practices daily. Continuous practice of Mantra purifies the consciousness and mind, and removes karma in much the same way as constantly walking over weeds on a path crushes them. Only those who continue to work with this gift form the spiritual master are able to harvest its fruits. If it is merely put away and “stored” it withers like flowers without water.
