This was written for the earthquake and tsunami that struck Japan in March, 2011, but the same visualization can be used in prayers for any country.
First do a general prayer for the whole world. You can pray in the way that Paramhansa Yogananda taught:
Divine Mother, Thou art omnipresent. Thou art in all Thy children. Manifest Thy healing presence in their bodies, minds and souls.
Then rub the palms together briskly and then hold up your hands and chant AUM three times, sending energy to the planet, and visualizing the planet floating in space between your divinely charged hands.
See Jesus Christ and Mahavatar Babaji surrounding the planet with Love and Light. See Divine Mother blessing all of her children and awakening them in Love.
Then think of Christ or Babaji sitting in lotus posture above Japan, lifting up the consciousness of souls. Ask for divine guidance and healing grace for all those affected by the tsunami and the nuclear radiation.
Paramhansa Yogananda wrote, in Chapter 33 of Autobiography of a Yogi:
[Babaji] is in constant communion with Christ; together they send out vibrations of redemption, and have planned the spiritual technique of salvation for this age.
The work of these two fully-illumined masters — one with the body, and one without it — is to inspire the nations to forsake suicidal wars, race hatreds, religious sectarianism, and the boomerang-evils of materialism. Babaji is well aware of the trend of modern times, especially of the influence and complexities of Western civilization, and realizes the necessity of spreading the self-liberations of yoga equally in the West and in the East.
