1. Om Asato Maa Mantra

ॐ असतो मा सद्गमय ।
तमसो मा ज्योतिर्गमय ।
मृत्योर्मा अमृतं गमय ।
ॐ शान्तिः शान्तिः शान्तिः ॥
Om Asato Maa Sad-Gamaya |
Tamaso Maa Jyotir-Gamaya |
Mrityor-Maa Amrtam Gamaya |
Om Shaantih Shaantih Shaantih ||

Meaning:
Asato-Maa, Sad Gamaya – From untruth to Truth! Untruth is the death of the ego. The Truth is eternal and immortal. So once you are part of the Truth, there is no question of death at all. My friends, the third barrier stopping enlightenment is the barrier of ego. Therefore, to experience God, we should see that the ego dies as early as possible.

Tamaso Maa, Jyotir Gamaya – There lies the light of wisdom. Tamas is the darkness. Jyoti is the light. With light, darkness is dispelled. Darkness is death. The light is Truth, Bliss, Peace. The light is eternal.
Mrityor maa, Amritam Gamayaa – Lead me from death to immortality through purity of purpose.
Aum peace, peace, peace!
