Mantras help link the self to the
higher Self by awakening or cultivating higher consciousness. Om Tat Sat is one of the most common mantras. The repetitive chanting of
this mantra encourages the mind to enter into a meditative state
so that the yogi may begin to connect with the higher Self or the
Divine within. It is believed to change the person's vibration.
Om Tat Sat is recited during religious practices, including the study of the Vedas and at the end of the yajnas (sacrifices). According to the Bhagavad Gita, all religious work or sacrifice should begin with the sound of Om. The sound of tat reminds the faithful to renounce any reward for the work or sacrifice. The sound of sat declares what is good and true, as is work that is done well.
This mantra is also used by yogis in
India as a greeting with hari (the manifest cosmos), as in “Hari Om Tat Sat.” The greeting is a reminder that individuals are more than
the body and earthly life.
