The most prominent realizer of Advaita Vedanta in recent time is still Ramana Maharshi. Here is something from David Godman, his chronicler, on Ishwara.
"The mind brings an illusory world into existence, dividing it into a seer and seen: a jiva who appears to inhabit the body, and an external world that is witnessed by it. When this projection takes place, Iswara, the God who supervises this creation, is also created. This God, the God who creates and sustains the world, is a mental creation, meaning that when the mind dies, the jiva, the world and God die with it, leaving Self alone. Iswara allocates karma to devotees and ensures that each devotee experiences the consequences of his and her actions. Here are some interesting answers that Paul Brunton elicited from Bhagavan on Iswara and his role in devotees’ lives:
Question: Is there a separate being Iswara who is the rewarder of virtue and punisher of sins? Is there a God?
Bhagavan: Yes.
Question: What is he like?
Bhagavan: Iswara has individuality in mind and body, which are perishable, but at the same time he also has the transcendental consciousness and liberation inwardly.
Iswara the personal God, the supreme creator of the universe really does exist. But this is only true from the relative standpoint of those who have not realised the truth, those people who believe in the reality of individual souls. From the absolute standpoint the sage cannot accept any other existence than the impersonal Self, one and formless.
Iswara, God, the creator, the personal God, is the last of the unreal forms to go. Only the absolute being is real. Hence, not only the world, not only the ego, but also the personal God are of unreality. We must find the absolute – nothing else.
