Thama-so Maa Jo-thir Gamaya
Mrith-yor Maa Amri-tham Gamaya

This means

Lead me from untruth to truth;
Lead me from darkness to light;
Lead me from death to immortality.
 

Another Powerful Prayer of St.Francis of Asissi

Lord, make me an instrument of thy peace
Where there is hatred, let me sow love;
Where there is injury, let me sow pardon;
Where there is doubt, let me sow faith;
Where there is despair, let me sow hope;
Where there is darkness, let me sow light;
Where there is sadness, let me sow joy;

O Divine Master, grant that I may not so much seek
To be consoled as to console,
To be understood as to understand,
To be loved as to love;
For it in giving that we receive,
It is in pardoning that we are pardoned,
It is in dying to self that we are born to eternal life.

        The above are just sample prayers from two spiritual traditions. You can chose a prayer from your own tradition and chant  everyday in the morning and in the night before bed. Chanting prayers will remove all the impurities of the mind, which means to bring the wandering mind to the present.

        Prayers have the power to help to transcend to the awareness state, which is also the source of Grace.
