Aarti (आरती) also spelled arati, arathi, aarthi (from the Sanskrit word aratrika with the same meaning) is a Hindu religious ritual of worship, a form of Puja. In Sanskrit “Aa” means “towards”, and “rati” means “the highest love for God”. By performing an aarti, one is expressing one’s devotion to God.
Here is Aarti collection(aarti sanghrah) with complete lyrics in hindi and english font with translation if available.
Aarti is said to have descended from the Vedic concept of fire rituals, or homa. In the traditional aarti ceremony, the flower represents the earth (solidity), the water and accompanying handkerchief correspond with the water element (liquidity), the lamp or candle represents the fire component (heat), the peacock fan conveys the precious quality of air (movement), and the yak-tail fan represents the subtle form of ether (space). When aarti is performed, the performer faces deity of God (or divine element, e.g. Ganges river) and concentrates on the form of God by looking into the eyes of the deity (it is said that eyes are the windows to the soul) to get immersed.
Aarti is waved in circular fashion, in clockwise manner around the deity. After every circle (or second or third circle), when Aarti has reached the bottom (6-8 o’ clock position), the performer waves it backwards while remaining in the bottom (4-6 o’ clock position) and then continues waving it in clockwise fashion. The incense represents a purified state of mind, and one’s “intelligence” is offered through the adherence to rules of timing and order of offerings. Thus, one’s entire existence and all facets of material creation are symbolically offered to the Lord via the aarti ceremony.
In Pooja/Aarti, Hindus pour or sacrifice things into the flame. Whether it be just the burning coals or cow dung or pouring of Ghee in the Flame. This Act Has a VERY DEEP MEANING in it. It is INTENTIONALLY offered to the fire.
