OK, I have made an attempt to bring together some ideas of what I think has been going on in India for thousands of years under what we call Hinduism, as a way of kick starting the discussion:
The Diversity of Hinduism
There is in Hinduism unity in diversity, meaning there is rationality in the conception of Hinduism as the way of life of a people. Nothing is ruled out, nothing is ruled in: reality can be anything. There is the freedom to search. This leads to diverse practices all of which are not just tolerated, but given respect for it is accepted that no one knows the truth for certain. People are entitled to their conceptions. The diverse practices that people engage in fit into a narrative of what Hindus are as a people and so what the homogeneity is composed of in terms of the unifying bonds between the different strands of practices. Hinduism is not ‘a’ particular way of life but the result of the practice of diverse ways of life based upon the recognition that there are different elements and facets to Nature and humans too are diverse in trying to relate to these from the limits of their perception with the majority focusing on particular aspects as it relates to their daily lives.
To address the issue of unity in diversity we need to ask why should there have been polytheism in Hinduism and it still persists in the 21st century. It persists because God does not try and change any of the conceptions that have been formed and are in the process of forming. Nature itself is diverse under one solar system. The relationships between different components of Nature are also varied yet unified into a system. Similarly, the human mind is diverse. We worship things that we need for our survival individually. From this train of thought we appreciate plurality and that there may well be gods for everything. There are also different ideas about reality. These are all formed by the human mind. They are attempts at fathoming reality. None are revelations from God. The only thing that God has ever done was to generate avatars who realised His existence and formulated various conceptions for society. God has let them do that because that is how He has created Nature to generate diversity within a whole. That is why Hinduism is so vast. In it we see the benefits of a pluralistic approach to the formation of society.
So how does it all fit together? When the full picture of Hinduism is not grasped the value that particular individuals place on their beliefs and accompanying practices will not be recognised by artificial scholars who look at superficialities instead of trying to understand how over thousands of years a people developed to become the Hindus of the world. Hinduism has everything in knowledge and devotional worship. Some sect exists with a conception of reality that is just right for its adherents. If you get fed up of it or just do not like it you go to some other sampradaya or parampara. They are all spiritual food for thought away from the mundane process of existing to live. People are striving for a spiritual existence above materialistic existence. And there is no animosity between the different conceptions because Hindus are freethinkers, each person having the right to work out what is true for himself. When you recognise different types of religions within Hinduism some formal and most informal, you can identify the adherents as being advaitists, vedantists, Shakta, Vaishnava, Shaiva, Smarta, or those who follow the teachings of particular Babas like Shiridi Sai Baba, Sri Sri Ravishankar, each carving out his or her own philosophy. Each person is going to a deity-based belief that meets his or her needs. One may have preferences for particular gods and beliefs but it is accepted that others may chose a different deity that gives them different types of strengths and comfort to cope with their lives. That is what society is about. Each person has a different character and strength (gunas) for which they are selecting the god that will best look after their needs which their minds will accept. There is room for no gods as atheists too. Every god-based belief is true in itself as they are derived from guna-consciousness energy created by God. So all paths are relevant and pertinent beyond criticism.
There is extensive literature on all the common sects for studies. There are astika or nastika lines of thoughts, that is those that take their authority from the Vedas and those that are independent of the Vedas. The Vedic verna-based caste system for the social stratification in society is also not universally adopted as seen in the existence of Dalits and the casteless. There was once widespread belief in astrology, which is nothing short than the worship of a god through another religion. The belief is now on its way out. There was also belief in karma that got transferred to new existences. That too is diminishing. Religions come and go.
The unifying theme in all spiritual practices is devotion. It is common to all of Hindu religions, that shows itself through worship, that is puja with or without idol worship; the striving of yoga and meditation. The method of yoga is also varies, one can be a jnana yogi as a householder, or one can become a renunciate as a sadhu on the banks of a river, or an Aghori baba. Society accepts these as legitimate pathways to determining truth. Each devotee chooses his own path and specific to the individual practices. They address different aspects of reality specific to the needs of the devotee.
Thus, no one forces anyone to be anything that they do not want to be. There are no holy books for all but sampradayas are free to compile their own literature that they will call scripture through a process of argumentation. That is the Hindu position which consequently evolves continuously and depending on the era and its level of scientific knowledge of Nature and the person doing the thinking and formulating it gets updated. Hindu society encourages free thinking and each person will therefore have his own ideas which will get a hearing. Some will be atheistic, others monotheistic or polytheistic etc. As time passes, old ideas may accordingly be completely dropped or modified and new ones formed. That is why we cannot tell what most of the gods currently represent. We can make them represent whatever we like and start a new religion. The unity in the diversity is given by the fact that the ideas exist side by side because they are propagated by individual adherents who will be at different stages of knowledge acquisition. The ideas are fostered by society so that people have a diverse range to consult and choose which one they adopt.
I too have an idealism that I have searched out during my truth-search phase. But I know that God has not sanctioned it as being God-approved. It is the best that I have come up from my years of almost constant communications with Him. I am not keen on getting it widely publicised for adoption. I have written my Blog about it and that is all that I will do. People have to do their own research into what I have written and formulate their own ideas on what reality consists of. That is how I wish to leave it.
