Obviously no other knowledge source has ever attempted to answer such questions and Upanishads give us the last word on all such matters. Through no other means is it possible for us to get convincing answers to our queries regarding them. Not being the work of man (Apaurusheya) they are free from the usual shortcomings of all human endeavor such as error, doubt, and deception. It is open to us all to verify their statements by actual experience along the lines prescribed by them. The truths inculcated in them are not mere theories, but facts, and as such are invulnerable.<ref>Swami Madhavananda author of A Bird's-Eye View of the Upanishads (1958) ''The Cultural Heritage of India, Volume 1 : The Early Phases (Prehistoric, Vedic and Upanishadic, Jaina and Buddhist).''

Shvetasvatara Upanishad in the very first instance puts forth these questions as deliberated by the Brahmavadins<blockquote>ॐ ब्रह्मवादिनो वदन्ति ।</blockquote><blockquote>किं कारणं ब्रह्म कुतः स्म जाता जीवाम केन क्व च सम्प्रतिष्ठा । अधिष्ठिताः केन सुखेतरेषु वर्तामहे ब्रह्मविदो व्यवस्थाम् ॥ १ ॥ (Shve. Upan. 1.1.1)</blockquote>People accustomed to deliberate on Brahman discuss : What is the nature of Brahman, the Source (किं कारणं ब्रह्म)? From what have been born (कुतः स्म जाता)? By what do we live (जीवाम केन)? And where do we exist, rest, at the time of dissoution (क्व च सम्प्रतिष्ठा)? O Knowers of Brahman, regulated by whom (अधिष्ठिताः केन) do we conform to the system regarding happiness and its opposite namely sorrows (सुखेतरेषु वर्तामहे)?

In this way the question "What is the cause" (किं कारणं । kiṁ kāraṇaṁ) pertains to the primordial cause of the regulation of creation, continuance and dissolution.<ref>Swami Gambhirananda (2009 Fourth Edition) ''Svetasvara Upanishad With the Commentary of Sankaracharya.''

'''Nirguna Brahma (Advaita)'''

'''Nirguna Brahma (Advaita)'''

'''Advaita Vedantins''' completely dismiss the concept that Brahman and Jagat (world) are completely distinct from each other and their tattva is explained in Shri Adishankara Bhashyas. Brahman is Nirguna, without attributes, and is Real; all else is unreal; Jivatma and Paramatma are the same without any difference. According to them the idea of difference arises from Avidya (nescience, ignorance, lack of yadartha jnana) and when Atma transcends Avidya, it brings about the realization of the All-ness and wholeness of the Atman as indicated by the vidya-sutra<blockquote>आत्मेत्येवोपासीतात्र ह्येते सर्व एकं भवन्ति । (Brhd. Upan.1.4.7)<ref>Brhadaranyaka Upanishad ([https://sa.wikisource.org/wiki/%E0%A4%AC%E0%A5%83%E0%A4%B9%E0%A4%A6%E0%A4%BE%E0%A4%B0%E0%A4%A3%E0%A5%8D%E0%A4%AF%E0%A4%95_%E0%A4%89%E0%A4%AA%E0%A4%A8%E0%A4%BF%E0%A4%B7%E0%A4%A6%E0%A5%8D_1a Adhyaya 1])</ref></blockquote>The Universe springs from Brahman, just like hairs on a man's head; it is the work of Maya. Cause and effect are one and the same (कार्यकारण-अभेदः) just like an aggregation of threads is seen in the form of a cloth. As long as the Atma identifies itself with the [[Upadhi (उपाधिः)|Upadhis]] (vehicle of atma), it remains bound in Samsara, when it Knows Itself as Self, it becomes free from Samsara. For those who are not yet ready for this effort of Self Knowledge, ritual is not only desirable but also necessary. Those who reached the point where Atma only attracts them, Jnanam is enough and by Sadhana they achieve Brahman, the goal. However, a Jnani does not abstain from Karma or actions (similar as in Samkhya siddhanta), he best understands them and actively engages in them, being unattached to the results and not by the dictate of desire. Such a person is called Jivanmukta.

For example, Chandogya Upanishad describes the unity of Jiva and Brahman, in the conversation between [[Uddalaka and Shvetaketu (उद्दालकः श्वेतकेतुः च।)|Uddalaka and Shvetaketu]]. Kathopanishad also proclaims that he who sees as though there is difference between the two (Jiva and Brahman) will be engaged in cycle of birth and death. Jnana that they are one and the same is to be attained through the Manas only. There is no diversity between the Jivatma and Supreme Brahman.  (Kath. Upan. 2.1.11)<ref>Swami Gambhirananda (1989 Second Edition) ''[https://archive.org/details/EightUpanishadsWithSankarabhashyamSwamiGambhiranandaVol11989/page/n198 Eight Upanishads, Volume 1 (Isa, Kena, Katha,and Taittriya)]'' Calcutta: Advaita Ashrama</ref>
