In Ramayan, during the war between Lord Ram and Ravana, Laxman ji became unconscious when he was hit by an arrow. Hanumanji brought the Sanjeevani herb, which was given to Laxmanji and he regained consciousness . Similarly, this is Sanjeevani Mantra, by chanting it whatever disease you may be suffering from, you will recover from it.

The entire universe with its animate and inanimate parts was created out of a divine word.
All the major religions in the world, despite their intrinsic mutual differences, hold a unanimous view that the entire universe with its animate and inanimate parts was created out of a divine word.
The Hindu or Vedic religion is no exception to this concept of God being the divine word of our origin. It acknowledges Om as the sacred syllable — the divine sound out of which God created this universe. Out of this divine word evolved variations of potent vibratory sounds capable of connecting with specific planes of cosmic consciousness on subtle level for which they were created.
“In the beginning was the word, and the word was with God, and the word was God. The same was in the beginning with God. All things were made by Him, and without Him was not anything made that was made. In Him was life, and the life was the light of men”— Bible
When mantras are directed to lower levels of consciousness they often end up as spells with destructive or protective powers. However, when they are used for reaching the higher planes of consciousness, they can take the practitioners to greater heights of spiritual awakening and eventual freedom from the cycle of birth and death.
There exists in India a secret knowledge based on sounds and the differences of vibratory modes according to each plane of consciousness.— “Sri Aurobindo or The Adventure of Consciousness” by Satprem
