Furthermore, the Ministry of Human Resource Development, Government of India, appointed him as the President of Adarsh Sanskrit Sanstha in Himachal Pradesh.
[13] Upadhyay's most notable work was Kalki Avatar and Muhammad[14][15] which was published in 1969 by Saraswat Vedanta Prakash Sangghha of Allahabad.
In addition, the book "Ovranto Boidik Shastrer Alokey Kolki Obotar" (অভ্রান্ত বৈদিক শাস্ত্রের আলোকে কল্কি অবতার, Kalki Avatar in the Light of Inerrant Vedic Scriptures) (2019), and the January–March version of Amriter Sandhane magazine, both published by Bangladeshi wing of Back to Godhead, criticizes the claimed resemblance to Kalki Avatar.
[50] Hindu spiritual leader Ravi Shankar claimed in his book "Hinduism and Islam: The Common Thread" that Muhammad is explicitly mentioned as the name "Mahamada" (Sanskrit: महामद) in Parva 3, Khand 3, Adhyay 3, texts 5-6 (Episode 3, section 3, chapter 3, text 5–6) of Bhavishya Purana: "An illiterate teacher will appear, Mohammed is his name, and he will give religion to the people of the desert", which also resembles the book.
Critics point out that the "Mahamed" described in the Bhavishya Purana is a "mlechcha" (foreigner, barbarian) and is the "Daitya" or "ghost" called Tripurasura' who is reborn.,[55] And the word "Muslim" has been said to mean a destroyer of religion.
[56] AK Ramanujan mentions Christ, Moses and Queen Victoria in a "properly updated Bhavisya Purana".
[59] Certain verses of the mantra are precisely identified and their semantic similarities are shown in order to create the context, mainly to prove Muhammad's prophecies.
A criticism of the claimed resemblance to Kalki Avatar is found in the book Ovranto Boidik Shastrer Alokey Kolki Obotar published by Amriter Sandhane Prakashani.
[60][56] Criticism states, Indian Hindu organisation Agniveer also judjed the book by the academic works of western scholars on Hinduism.
According to the organisation, the book presents the story of Abrahamic Adam and Eve, Noah, described in the Pratisarga episode of Bhavisya Purana.
Ziaur Rahman Azmi in his book "Dirasat fil Yahudiyat wal Masihiyat Wal Adianil Hind" (دراست في اليوديه والمسيحيه واديان الحند, Studies on Judaism, Christianity and Indian Religions) stated that, although most of the mainstream Muslim scholars do not regard Hindu scriptures as divine scriptures revealed from God rather than man-made Aryan literature, there may be three reasons behind the "possible" inclusion of Islamic prophecies in Hinduism.
[15] Azmi Also said that, some Hindus including the founder of Arya Samaj Dayananda Saraswati and his followers also consider these to be fabrications.
"[89]Zakaria also criticized the book, saying that Narasangsha is described in verse 127 of the 20th volume of the Atharveda as Kalki which is not the main body of the Atharvaveda, he said that it is an anticipatory portion (Prakshipta Angsha or later interpolation) and subsequent connections, and said that prophecies of Muhammad in Hindu scriptures were used by Hindus to make their scriptures acceptable to Muslims, which is a clever attempt, beginning with Akbar's reign to flatter Emperor Akbar by writing the Allopanishad, he claims that the Bhavishya Purana is completely fabricated and man-made with Hindu references.
In addition, all Hindu scriptures, including the Vedas, are claimed to be adaptations of the beliefs of the migrated Japhethite Aryans (Zoroastrians and Rigvedians), indigenous Hemite Dravidians, and other Indo-European classical mythologies along with the influence of monotheism taken from Avestan concept of Ahura Mazda influenced by tha geographically adjacent Arabian Semitic people, as he claimed that, ancient Dravidian Indians were the descendant of Ham, one of the sons of Noah, and the Aryans were the descendants of Japheth, another of the three remained sons of Noah after the Biblical great flood, This is what historians have mentioned regarding the origin of the people of India, although the truth of the matter is that all are from Adam, and Adam is from dust, and God has destroyed the children of Adam except for Noah's children.
And as Hinduism established itself as a conformist and syncretistic doctrine from the Islamic point of view, he claimed that, all Hindu scriptures are not inspired but man-made Aryan literature and the theory that this book attributed Kalki to Muhammad was a false and deceitful attempt.
