First, know that Advaita is not a philosophy to argue.+

Krishna Chaitanya Q:~ Dear sir, how as per Advaita, you can explain the natural disasters like earthquakes, tsunami, etc, fatal diseases, accidents, in which thousands of innocent, good people die or suffer? May you post an article explaining this one on Facebook?

A:~ Santthosh Kumaar: ~ First, know that Advaita is not a philosophy to argue. Advaita is the nature of the Soul, the  Self. The Soul is the cause of the universe in which we exist, and it itself is uncaused. The whole universe is created out of single stuff. That single stuff is the Soul, which is present in the form of consciousness. The Soul is the ultimate truth or Brahman or God. From the standpoint of the Soul or God, the universe is merely an illusion. 

Therefore, the natural disasters like earthquakes, tsunami, etc, and fatal diseases, accidents, in which thousands of innocent, good people die or suffer, is within the dualistic illusion or Maya. 

Suppose, if you had asked me the same question in a dream, the dream becomes unreal when the waking takes place. Similarly, the waking becomes unreal the waking (universe) becomes unreal when wisdom dawns. Wisdom dawns when you realize the ‘Self’ is not you, but the ‘Self’ is the Soul, which is God, which pervades in everything and everywhere in the universe in which we exist. Thus, everything is the Soul, which is God. The nature of God is Advaita. 

If one says this universe is real then:~ 

A person, who stamped his foot on the ground to refute to show the world, is real, ignore that in a dream he would do exactly the same--stamp his dream foot on the ground and assert it to be real. 

Gnani and Illusion:~ 

A King who was greatly incensed at the wisdom taught by Gnani that everything here below is an illusion. He wanted to teach the exponent of this doctrine a lesson. So he invited the then Gnani to his palace. That Gnani went there and stoutly maintained that everything in this world is an illusion. 

The king had arranged to let loose a hungry lion against Gnani. The beast rushed at Gnani who took to a precipitate flight to save himself. 

'Oh, Venerable Sir,' shouted the king, 'why do you run so fast seeing that the lion is only an illusion?' 

'Oh, king,' said Gnani in the course of his flight, 'my running too is an illusion. Everything in this world is an illusion.’ 

Similarly, natural disasters like earthquakes, tsunami, etc, and fatal diseases, accidents, in which thousands of innocent, good people die or suffer, is within the dualistic illusion. The dualistic illusion is created out of single stuff and that single stuff is Soul, which is present in the form of the consciousness. Knowledge of the single stuff is Self-knowledge or Brahma Gnana or Atma Gnana. 

The universe is a reality from the dualistic perspective. on the nondualistic perspective, the universe is merely an illusion created out of the Soul, which is present in the form the consciousness. 

We all are searching truth within the dualistic illusion or Maya not being aware of the fact that the illusion is created out of single stuff. That single stuff is the Soul, which is present in the form of consciousness.

Thus, searching the truth in the illusion with the illusory Self, within the illusory experience, has to be an illusion. The illusion is created and sustained and finally dissolves as the Soul or the consciousness. There is no second thing other than consciousness. Thus, consciousness is the ultimate truth or Brahman or God. 

That is why one must realize the Soul is the real God. 

Lord Krishna Says Ch ~V: ~ “Those who know the Self in truth.". The last two words (tattvataha) are usually ignored by pundits, but they make all the difference between the ordinary concept of God and the truth about God. 

The Bhagavad Gita: ~ Brahmano hi pratisthaham ~ Brahman (God) is considered the all-pervading consciousness, which is the basis of all the animate and inanimate entities and material. (14.27). 

When Bhagavad Gita says, God is considered the all-pervading consciousness which is the basis of all the animate and inanimate entities and material then nothing has to be accepted as God other than consciousness. 

The dualistic worship of "God” is only for the ignorant populace. The God in truth is only Atman, the innermost Self. In reality, there is no duality, no differentiation. Only Atman exists. 

Yajurveda – chapter- 32:~  God is Supreme Spirit. 

If God is the formless Spirit, then how does man know God created the world? There is no proof. If the man had seen God creating the world, he could admit it, but how could he have seen God before he came into existence? (i.e. were created). 

The Vedas confirm God is Atman (Spirit), the Self. 

Rig Veda: ~ 'Prajnanam Brahma'- Consciousness is the ultimate reality or Brahman or God in truth.

God in truth is the Atman, the Self. Atman is present in the form of consciousness.

Do not accept any other God other than Atman not worship other than Atman.

Let these words be inscribed in your subconscious.

Nothing is real but God. Nothing Matters but love for God in truth. God in truth is everywhere and in everything.

God in truth is hidden by the illusory universe. God in truth alone is and all else is an illusion. 

Rig Veda: ~ The Atman is the cause; Atman is the support of all that exists in this universe. May ye never turn away from the Atman, the Self. May ye never accept another God in place of the Atman nor worship other than the Atman?" (10:48, 5) 

Rig-Veda 1-164-46 and Y.V 32-1 clearly mention that God is “One”. 

Rig Veda declares God is ‘ONE’ and God is Atman, then why believe and worship in place of real God. 

Brihad Upanishad: ~ “If you think there is another entity, whether man or God there is no truth." 

Brihadaranyaka Upanishad: ~ Brahman (God) is the form of the Athma, and it is indeed Athma itself. 

People who are saying ‘I Am GOD’ are hallucinating that they become God. First, you must know what is God. 

When Upanishad itself declares: ~ Sarvam khalvidam brahma ~ all this (universe) is verily Brahman. By following back all of the relative appearances in the world, we eventually return to that from which it is all manifest – the non-dual reality (Chandogya Upanishad). 

Sage Sankara’s Supreme Brahman (God in truth) is impersonal, Nirguna (without Gunas or attributes), Nirakara (formless), Nirvisesha (without special characteristics), immutable, eternal, and Akarta (non-agent). It is above all needs and desires. It is always the Witnessing Subject. It can never become an object as it is beyond the reach of the senses. Brahman is non-dual, one without a second. It has no other besides it. It is destitute of difference, either external or internal. Brahman cannot be described because the description implies a distinction. Brahman cannot be distinguished from any other than It. In Brahman, there is not the distinction of substance and attribute. Sat-Chit-Ananda constitutes the very essence or Svarupa of Brahman, and not just Its attributes. The Nirguna Brahman of Sage Sankara is impersonal. 

Sage Sankara: ~"That which permeates all, which nothing transcends and which, like the universal space around us, fills everything completely from within and without, that Supreme non-dual Brahman or Godin truth." 

Thus, truth realization is Self-realization. Self-realization is God-realization. God-realization is real worship.  :~Santthosh Kumaar
