Chaturbhuja

Chaturbhuja is a concept in Hindu iconography in which a deity is depicted with four arms. Several Hindu deities are often portrayed with four arms in their iconography, featured in Hindu literature. The iconography of four arms is regarded to symbolise divinity and power, as well as dominion over the four quarters of the universe.
Chaturbhuja is also primarily employed as an epithet for the preserver deity, Vishnu.
Description
The earliest Vaishnava images, according to scholar Gavin Flood, are of a standing two or four-armed figure bearing a combination of the attributes of a conch, a wheel, and a mace in their iconography. This multiplicity convention, in which deities bore numerous limbs and heads in their imagery, was established in the Mathura region, before becoming a custom in later Hindu iconography.
According to author Nanditha Krishna, the chaturbhuja representation of Hindu deities in their icons is regarded to depict their unlimited potential. It exhibits their divine ability to wield multiple articles, such as weapons, and perform numerous activities simultaneously.
Indologist Doris Srinivasan states that in both Vaishnava and Shaiva imagery, the Chaturbhuja form is regarded to be the manifestation of a deity who descends upon the earth and performs auspicious acts for the well-being of mankind, typically receiving the veneration of human beings.
Examples
