Soham Mantra
       

Natural mantra: The Soham mantra is a natural mantra because it is already part of your nature.         

• Sooooo... is the sound of inhalation, and is remembered in the mind along with that inhalation.
  
  
• Hummmm... is the sound of exhalation, and is remembered in the mind along with that exhalation.
  
  

Universal mantra: The Soham mantra has been called the universal mantra because of the fact that its vibration is already a part of the breath, and everybody breathes. Sooooo... is the sound of inhalation, and Hummmm... is the sound of Exhalation

Soham is the cristallisation of OM in the breath.
