The nitrogen compounds through which excess nitrogen is eliminated from organisms are called nitrogenous wastes (/naÉªËtrÉdÊáµ»nÉs/) or nitrogen wastes. They are ammonia, urea, uric acid, and creatinine. All of these substances are produced from protein metabolism.
A diya, divaa, deepa, deepam, or deepak is an oil lamp, usually made from clay, with a cotton wick dipped in ghee or vegetable oils.Clay diyas are often used temporarily as lighting for special occasions, while diyas made of brass are permanent fixtures in homes and temples.iyas are native to India, and are often used in Hindu, Sikh, Jain and Zoroastrian religious festivals such as Diwali or the Kushti ceremony. A similar lamp called a butter lamp is used in Tibetan Buddhist offerings as well.
The oil in the diya represents the dirt (greed, jealousy, hatred, lust etc) that humans tend to nurture while the cotton wick is symbolic of the aatman (self).So in order to attain enlightenment and unite with the Brahman (the supreme power), one must get rid of materialism.n ignorant person would often remain in dark and wouldnât be able to keep a check on the events happening around him. It is only when he feels the need to gain some knowledge that he will realise the purpose of his existence. And hence in this case, a diya/jyot signifies the removal of ignorance through knowledge.
