Brahman is the ultimate reality, it is simultaneously Saguna and Nirguna, divisions are due to ignorance. Mind and intellect can never catch hold of it, they have only one option and that is to merge with it.
Never during its pilgrimage is the human spirit completely adrift and alone. From start to finish its nucleus is the Atman, the god-within... underlying its whirlpool of transient feelings, emotions, and delusions is the self-luminous, abiding point of the transpersonal god. As the sun lights the world even when cloud-covered, “the Immutable is never seen but is the Witness; it is never heard but is the Hearer; it is never thought but is the Thinker; it is never known but is the Knower. There is no other witness but This, no other knower but This. from the Upanishad
Om is that God of love. Like a loving mother Om cleans us of our clutters collected through many incarnations.
As the sun, revealer of all objects to the seer, is not harmed by the sinful eye, nor by the impurities of the objects it gazes on, so the one Self, dwelling in all, is not touched by the evils of the world. (The Upanishads: Breath of the Eternal, pg. 35)
As fire, though one, takes the shape of every object which it consumes, so the Self, though one, takes the shape of every object in which it dwells. (The Upanishads: Breath of the Eternal, pg. 35)
As per the Indian philosophy of the Upanishads, the source of evil is one’s ego-sense –Ahankara—which differentiates oneself from the other selves. A person, who visualizes himself independent of others, tries to guard or please himself at the cost of others. Evil is thus the tendency of a person to live a life that is not ‘in harmony’ with the rest of the world, but ‘in opposition’ to it or at best ‘in indifference’ to it. The good is to discover the unity in the diversity of ‘all selves’ and beings. Once unity in diversity is realized, every being becomes our own self and good deeds follow automatically
It is said in the Upanishads: ‘I am the Universe.’ If you ask a hundred people as to how they find the world, they are all likely to give different answers. For some, the world is beautiful and the people are good, while for others, the world is extremely bad, and the people are treacherous and sinful. Why the same world is different for different people? It is so, because the outer world is the projection of our inner world. Therefore, the only way to improve the world outside is to improve the world within. While we may not have any control over the outside world, we can change our world within and thus change the world outside.
