Garuḍa is the giant eagle, the vehicle of Lord Viṣṇu. He is also the possessor of supernatural powers and is feared by the demons (those with dark energy). This is why he is called Kṣipa, one who is strong, fierce and fast. Yogi-s invoked Garuḍa to destroy enemies and dark forces that affected them through invoking this Garuḍa mantra.
Chant this 12 times at dawn and dusk, thinking of this mighty bird, and asking him to remove the enemies that reside in your heart - lust, anger, greed, delusion, envy, jealousy, fear, ego and other such dark forces.
Namaste!!!
oṁ kṣipaḥ svāha
