Om stands for the comprehensive energy of the entire universe. Mani stands for compassion and love, and Padme (or Peme) for wisdom. The syllable Hum (or Hung) denotes the indivisibility of method and wisdom, through which the energy of the universe can be realized on the human level.
Mantras are powerful sound energies in Sanskrit, a prayer and chanting language.
The proper use of these sound energies helps to achieve health, inner harmony, mental clarity, powerful life energy, unfoldment of love and joy. The highest goal of Mantra Yoga, as always in yoga, is the realization of the true nature, the oneness with the infinite life itself. Mantra Yoga is considered one of the most powerful, easiest, safest and fastest ways to this realization.
