In Hindu culture our rituals do not complete without lightening diya or lamps. It is way of spreading joy, prosperity and brightness.It also helps to remove negativity from the atmosphere and your surroundings.It hepls to attract possitive energy from the enviroment.
The lamp has its own special place in Sanatan Vaidik Hindu Dharma. It is a form and a symbol of Tej (Absolute fire principle). The lamp is invoked as, ‘तमसो मा ज्योतिर्गमय ।’ meaning the lamp leads us from darkness towards light. It burns only to give message of peace and light to the man. This is its greatness. The following mantra which is recited during the ritual of puja explains its significance.
भोदीपब्रह्मरूपस्त्वं ज्योतिषांप्रभुरव्यय: ।।
आरोग्यंदेहिपुत्रांश्चमत:शांतिं प्रयच्छमे ।।
Meaning: O Deity of lamp, you are of the form of Bramhan (the absolute truth). You are full of radiance. You never wither. Please bestow me health and good progeny and please fulfill my wishes.
Ghee lamp has more capacity to attract the sattvik vibrations present in the surrounding atmosphere as compared to oil lamp. When the oil lamp stops burning the predominance of raja particles in the atmosphere is enhanced and lasts for half an hour. On the other hand when the ghee lamp stops burning the impact of sattvikta (the quality of being sattvik) on the atmosphere is experienced even after four hours. The oil lamp generates a subtle armour of inferior quality around the worshipper while ghee lamp generates a subtle armour of superior quality.
