All religions are man-made. The background to how religions developed was discussed here: https://satyaadvaita.wordpress.com/2013/09/30/the-evolutionary-basis-of-religious-conflicts/.
It has previously been proposed that the human mind derives its influences from guna consciousness and that this is the basis of human behaviour (https://satyaadvaita.wordpress.com/2014/01/25/how-does-hinduism-explain-evil-conduct/). It is human conduct that generates beliefs and practices that together form religions and philosophies by which people live. Thus, all religions are developed and propagated by different human mentalities belonging to the sattvic, rajasic and tamasic gunas or from a blend of these. The task therefore is to determine which of the world religions take its inspiration from which aspect of guna consciousness.
It would appear that Hinduism is sattvic on the basis that it focuses on truth and the attainment of dharma based on truth determination. The fact that God came to me and led me to finding my Hindutva as a satya-advaitic person shows that this is the religion that is fully blessed by God (Sri Krishna). I have been determining the central pillars of Hinduism through my blog through careful consultation with God. This is why I know that Hindutva is sattvic governed by Brahma. Sikhism and Judaism are also likely to have been founded by sattvic minds.
Christianity is full of lies and focuses on individual’s attaining sainthood through their dealings with fellow human beings. It shows an entirely different way of living not based on dharma but on worshipping a Jesus Christ in which quite normal human behaviour is treated as sins not fitting into the commandments. It therefore could not have been imagined by a sattvic mind or minds. It is however not a violent and oppressive religion so may be derived from rajasic guna, governed by Vishnu.
Buddhism is not sattvic because only sattvic people find the truth about God’s existence. Just like Christianity, it is also not a violent and oppressive religion so is likely to have been derived from a rajasic person (the Buddha). The Buddha is not an avatar of Sri Krishna.
Islam is oppressive and violent and must have been derived by tamasic guna, governed by Shiva.
31 July 2014 Update: Following further truth-seeking studies with God using clock checking to get to the truth, I have learnt that the only religion created by God (Sri Krishna) for the land of Asia south of the Himalayas is the original religion of Hinduism. All the others are derived from the guna consciousness gods of Brahma, Vishnu and Shiva. Of these Christianity, Buddhism and multiculturalism are divine or sattvic religions inspired through Brahma, whereas Islam and modern Judaism are evil or tamasic religions inspired through Shiva. Hinduism is therefore the overriding religion. It should however be noted that the ‘Ten Commandments’ was inspired by Sri Krishna to Moses. When this Judaism went astray Christianity developed and spread rapidly because it was divine.
6 August 2014 Update: Atheism and Islam are tamasic (Shiva-generated), Sikhism and secularism are rajasic (Vishnu-generated), Buddhism and Christianity are sattvic (Brahma generated): only ‘dharma’ is given to humans by God Sri Krishna as the Creator and Preserver of the universe. Dharma is given to us by God, Sri Krishna for the benefit of nature and transcends guna-consciousness. Hinduism, that is the spiritual and religious practices of the Hindus, needs to be re-assessed accordingly.
What is param dharma? Is it to always be truthful and uphold truth rather than practicing ahmisa (non-violence to sentient beings) as revealed in the shloka of the Mahabharatta ‘ahimsa param dharma hai, lekin dharma ki raksha ke liye himsa karna sorvottam hai’? No truth and upholding truth is not the highest dharma for one can lie and suppress truth (censorship) in order to protect righteousness and oneself from danger, especially during the course of warfare. Thus, God had also said to Moses: thou shalt not kill. Life itself is a struggle for the performance of duties and righteous actions as dharma. Dharma means to live to reality: and that reality is that God does clarify to us humans what is the truth. This He has done through the shloka in the Mahabharrata on ahimsa being the most important of the do’s and don’ts of dharma which he facilitated my investigation of in relation to why this is a rationale that fits into the reality of the nature of the environment in terms of what Earth is composed of. God lies inside all living beings but does not respond to ordinary people who rely on guna consciousness-derived religions for their inspiration on how they should live: He only responds to those practising dharma and this is why the full Mahabharrata shloka ends with ‘dharma rakshati rakshita’.
25 August 2014 Update: http://en.wikipedia.org/wiki/Gu%E1%B9%87a states:
The Triguna appear prominently in the discourse of Krishna to Arjuna upon the battlefield of Kurukshetra that is the backdrop for the Bhagavad Gita. All three gunas are held to delude the World: त्रिभिर्गुणमयैर्भावैरेभिः सर्वमिदं जगत्।मोहितं नाभिजानाति मामेभ्यः परमव्ययम्॥ ७.१३॥tribhirguṇamayairbhāvairebhiḥ sarvamidaṁ jagat |mohitaṁ nābhijānāti māmebhyaḥ paramavyayam || 7.13||The World deluded by these Three Gunas does not know Me:Who is beyond these Gunas and imperishable. (7.13)
I was unclear on how to translate or interpret rather the word rajasic in English language so had left it loose as meaning ‘semi-divine’. What I mean now by rajasic in describing human behaviour is that which is ‘routinal’, that is, habitual or the following of a normal course of performing ones duties in the material world. That is as far as I have got on this research. However, now I see that Peter Wilberg has made his own study of Gunas in human nature which one needs to take account of: http://www.thenewyoga.org/GUNAS.pdf.
