Shanti Mantra

The Shanti Mantras or "Peace Mantras" are Hindu prayers for Peace (Shanti) found in Upanishads. Generally they are recited at the beginning and end of religious rituals and discourses.

Shanti Mantras are invoked in the beginning of some topics of Upanishads. They are supposed to calm the mind of the reciter and environment around him/her. Reciting them is also believed to be removing any obstacles for the task being started.

Shanti Mantras always end with three utterances of word "Shanti" which means "Peace". The Reason for uttering three times is for calming and removing obstacles in three realms which are:

According to the scriptures of Hinduism sources of obstacles and troubles lie in these three realms.

These are called "Tapa-Traya" or three classes of troubles. When Shanti mantras are recited, obstacles fr om these realms are believed to be pacified.

These are the Shanti Mantras from the different Upanishads and other sources.

ॐ पूर्णमदः पूर्णमिदम् पूर्णात् पूर्णमुदच्यते |
पूर्णस्य पूर्णमादाय पूर्णमेवावशिष्यते ||
ॐ शान्तिः शान्तिः शान्तिः ||

Auṃ pūrṇamadaḥ pūrṇamidam pūrṇāt pūrṇamudacyate
pūrṇasya pūrṇamādāya pūrṇamevāvaśiṣyate
oṃ śāntiḥ śāntiḥ śāntiḥ

Aum! That is infinite ([[

Man]]), and this (universe) is infinite.
The infinite proceeds from the infinite.
(Then) taking the infinitude of the infinite (universe),
It remains as the infinite (Brahman) alone.
Aum! Peace! Peace! Peace!

ॐ शं नो मित्रः शं वरुणः।
शं नो भवत्वर्यमा।
शं न इन्द्रो बृहस्पतिः।
शं नो विष्णुरुरुक्रमः।
नमो ब्रह्मणे। नमस्ते वायो।
त्वमेव प्रत्यक्षं ब्रह्मासि।
त्वामेव प्रत्यक्षम् ब्रह्म वदिष्यामि।
ॠतं वदिष्यामि। सत्यं वदिष्यामि।
तन्मामवतु।
तद्वक्तारमवतु।
अवतु माम्।
अवतु वक्तारम्।
ॐ शान्तिः शान्तिः शान्तिः॥
