Ishvara is a term in Hindu philosophy that refers to a personal god or supreme being. It is often associated with the concept of a creator and sustainer of the universe. In various texts, Ishvara is depicted as the ultimate reality, embodying both the immanent and transcendent aspects of divinity. In the context of Vedanta, Ishvara is seen as the controller of the universe, guiding the laws of nature and the fate of all beings. This concept is significant in the teachings of Bhagavad Gita, where Ishvara is identified with Krishna, emphasizing the relationship between the divine and the individual soul.
