The root of the word also implies descent from a high place. Angels are beings who build relations between the macrocosmic world and the material one, and convey the commands of God, superintend or direct the acts and lives of beings and represent their worship in their own realms. Angels move very rapidly and permeate all realms of existence Having refined or subtle bodies of light, angels move very rapidly and permeate or penetrate all realms of existence. As they place themselves in our eyelids or in the bodies of other beings to observe the works of God through our or their eyes, they also descend into the hearts of the Prophets and saintly people and breathe inspirations into them. The inspirations occurring to the hearts of saintly people are usually from God but they may sometimes be from angels.
Science is unable to explain what an impulse is and how it occurs.
Even if we attribute this to the information coded into their DNAs, this information is assuredly from God, Who knows everything and controls all the universe, and angels deputed for such creatures direct their lives. If it is a scientific attitude that we unquestionably accept the existence of some invisible forces like the law of growth in living creatures, then it will be more scientific to attribute those forces to God's special servants, that is angels. Each thing in existence, whether universal or particular, has a collective identity and performs a unique, universal function. As each flower displays a superlative design and symmetry and recites, in the tongue of its being, the Names of the Creator manifested on it, so the whole earth performs a universal duty of glorification as though it was a single flower. Likewise, the vast 'ocean' of the heavens gives praise to and glorifies the Majestic Maker of the universe through its suns, moons and stars.
