It is believed that Sesame was produced from the body of Kashyap Rishi and hence all the grahas, devatas and pitras become pleased when a person offers sesame oil to them. As per Hinduism, Sage Kashyap is considered the son of Lord Brahma and Fatherly Guru of every living being.
It is done through using it in a holy bath, or by donating sesame seeds or oil and by using it in havan or lighting lamps of sesame oil.
It is advised to light the lamp of sesame oil in the evening to reduce the ill effects of planets and get the blessings of favourable planets.
Shani and Rahu being the most feared planets by humans for their ability to do harm to the individual in a bad phase, is known to calm down with the use of sesame oil in puja as the planet Shani belongs to the Kashyapa clan and sesame is derived from Sage Kashyap.
Hence people light the sesame oil lamps in homes and temples especially during Saturday after sunset to get the benefits of their worship.
Sesame oil is also known as til oil or gingelly oil is regarded widely as the queen of oils.
This is due to its multifold benefits of sesame oil in cooking, medicinal use and also in the traditional puja rituals in Hindu tradition.
Sesame oil is widely known for its medicinal use in controlling blood sugar and blood pressure due to the rich presence of antioxidants (lignans, gamma-tocopherol).
Also in Ayurveda, it is used to reduce stress-related problems. It is also used in various massages.
Sesame oil is also one of the most used cooking oil in many parts of the world. But its most effective use in puja in Hindu rituals is due to the fact that it is considered the best remedy for Saturn and Rahu related ill effects.
