Why is red flower offered to Ma Durga ?

One prominent objective of worshipping a Deity is that the devotee should derive optimum benefit for his spiritual progress from the Chaitanya (Divine consciousness) in the idol of the Deity. Specific flowers have better ability to attract the subtlest particles of a specific Deity’s principle. Naturally, when these flowers are offered to the Deity during worship, they help awaken the idol and the devotee benefits from the Chaitanya in the idol. Hence, the importance of offering red flowers to Ma Durga. In reality it is the specific fragrance and specific colour from the flower that attracts the Deity’s principle.- Tanuja Thakur
