Why do we perform aarti
Towards the end of every ritualistic worship (puja or bhajan) of the Lord, we perform the aarti. This is always accompanied by the ringing of the bell and sometimes by singing, playing of music.
It is referred to as the auspicious light. Holding the lighted lamp in the right hand, we wave the flame in a clockwise circling movement to light the entire form of the Lord. Each part is revealed individually and also the entire form of the Lord. As the light is waved we either do mental or loud chanting of prayers or simply behold the beautiful form of the Lord, illumined by the lamp. We experience an added intensity in our prayers and the Lord’s seems to manifest a special beauty at that time. At the end of the aarti we place our hands over the flame and then gently touch our eyes and the top of the head. The philosophical meaning of aarti – the sun, moon, stars, lightning and fire are the natural sources of light..Therefore as we perform the aarti chant.It is there where the sun does not shine, Nor the moon, stars and lightning then from this small flame everything shines in front of Lord and by his light alone,we all illumined.

Why should we light earthen (mitti diyas) lamps – The mystery of Divine earthen (mitti) Lamp 
When we light the earthen lamp there is combination of Five Divine Tattwas i.e. Soil (Earth, Fire, Air, water & Ether) & we chant the Mantra of Lord so it manifests divinity in our family.
Also, these lamps are made by potters with faith, emotion & feeling of Love for God & Goddess. These are made clay of the Divine Soil i.e. “Earth Element”
Thus,when we light earthen lamps on Festival like deepawali, govardhan puja and other pujas, we bring in the positivity.
