Brahmanic and Vedic symbology

[Vkothii]

I have a question about an image (also seen in an image of Krisna), where three-headed Brahma is seen holding four objects, one in each of his four hands.

They appear to be a sceptre, a lotus, a gold ring (around one finger in the Krisna image), and a conch shell.

I think the conch is meant to represent the sound of Brahma, and the golden ring is light. What does the lotus or sceptre signify, though?

What's your take?

 

[Eidolan]

The lotus probably signifies peace and maybe death and/or sleep or other related states of rest. The scepter is probably authority. However, I really don't know.
