Which oil  is superior to lit the lamp  for the worshipping the God ?

All of us lit the lamp with oil and do the pooja for the God or Goddess in 

normal days and festival times. It is said in scriptures and from the vedic

 scholars the customs and duties for that.

The cow’s ghee is the superior than any other  to lit the lamp. The gingily 

oil is next best and the least is the oil from Bassia tehfolia 

(Ippa Pushpa or Madhuka Pushpa in Sanskrit language) flower.

The result or consequence is the most if we worship the God with cow’s

 ghee lamp. It is said those who worship with the cow’s ghee they will be

 bestowed by Ashtabhogas and Ashta Iswaryas.

If we worship in the Pramidas (mruddipah in sanskrit language) 

made of the Panchaloha or Silver or Mud are the best.

If one who lits  the pooja lamp with the castor  oil , they will get happy 

family life and get all other comforts in life.

Under any circumstances one should not do the worship with the 

Groundnut oil which is dosha.

If we worship the Goddess Sri Mahalakshmi with the cow’s ghee which is

 Gracious for Her.  If we do the pooja with gingily oil lamp for God,

 Ganesh (Vinayaka) that would be a  Gracious for Him.
