Kṛṣṇa completes the hierarchy of existence. After mentioning the fallible and infallible souls, He introduces the ‘Uttama Puruṣa’—the Supreme Person, who is also known as the Paramātmā. He is the one who enters the three worlds and sustains all beings. He is the ‘Īśvara’—the imperishable Controller. This is the definitive answer to the question of ‘Who is God?’. He is not just a soul that has become ‘more’ evolved; He is an entirely distinct, superior category of person. While we are supported, He is the Supporter (‘Bibharti’). While we are limited to our own experience, He enters every world and every heart to manage the cosmos. This verse prevents the mistake of thinking that we are all God. We are small parts, but He is the Whole. He is the ‘Uttama’ (the Best), and our perfection lies in aligning ourselves with His will. This realization provides the soul with its ultimate shelter, knowing that a perfect, loving Master is personally maintaining the entire universe.
