Which oil is used in Diwali lamps?

Mustard oil or sesame oil is used to light up the Diwali lamp as it helps to nullify the effect of evil spirits. It also helps to boost knowledge and prosperity in the home. As a result, using sesame oil for burning diyas has a great deal of importance in Hindu culture. Moreover, if you wish to receive the best results, the right choice can include pure coconut oil. However, while using the same, avoid placing the same in the south direction as the same is considered as the direction of Lord Yama. So, due care must be given to the kind of oil that you have used and the ideal way to light up the same.
