The concept of a single "greatest" God is complex and depends entirely on individual belief and religious tradition. Within Hinduism, for example, different traditions elevate different deities to the supreme position.
- Vaishnavism: Followers of Vaishnavism consider Vishnu to be the supreme Paramatman.
- Shaivism: Followers of Shaivism consider Shiva to be the Supreme.
- Shaktism: Followers of Shaktism consider Adi Parashakti to be the supreme.
These differing views reflect the understanding that Ishvara, Bhagavan, Bhagvati, Parmeshwara and Paramatman are all names denoting aspects of Brahman, the ultimate reality. Therefore, claiming one God as universally "greatest" is not possible within this framework, as they are ultimately considered different manifestations of the same underlying divine principle.
In monotheistic religions like Christianity, Islam, and Judaism, there is a single, supreme God, and therefore the concept of a "greatest" is inherent. However, these religions hold fundamentally different beliefs about the nature and attributes of this God.
Ultimately, the answer to the question "Which God is greatest of all time?" is subjective and depends on one's personal faith and theological perspective. No single answer can be universally applied.
