Gurudev, Brahma is the creator, Vishnu is the maintainer and Shiva is the destroyer. Why do we pray so much to the destroyer only?
The creator has finished his job, so, nobody cares for him. The maintainer is necessary, and everybody is afraid of the destroyer!
No, it is not like that. The God of all Gods is Shiva, Mahadev, therefore, everyone worships Mahadev. Brahma was born out of Vishnu. In this way, there are different beliefs in all different cultures, you believe whatever you like.
