Business and management gurus would tell you that remarkable pace and progress is achieved when the management and business works as a unified mind.

Think of a business owner who knows the in and out of business, what to buy, what to sell, who to sell, how to sell, how to manage and other things. The business owner has a brain. The business owner delegates some parts of his brain to his employees and staff so that they could also function in his organization without needing to check with the business owner again and again.

The more the business owner is able to delegate his brain to his staff, the more automated the staff would become. The better the organization can function and there can be rapid pace, progress and expansion of the organization.

Similarly Hindu unity can be achieved when there is a single Hindu brain. Earlier, when perhaps there were a lot of factions in Hindu society, Jagadguru Sankaracharya rose to the occasion and explained to Hindus that it's non-dualistic advaita. There are no dividing lines, like classes or castes. There are no hierarchies, groupings, identities, etc., as these are just temporary ossifications of thoughts and ideologies which people start identifying with as reality.

Sankaracharya did not do something like create a new ideology. Just presented reality as reality. The ultimate truth alone is God. We do not claim to know God exists beyond our reality. Advaita simply suggests dissolve and dilute all the unreal manifestations that are temporary and which we falsely believe as the truth. After such dissolution alone can you reach the actual truth, and once you reach that you will realize God.

If every Hindu is able to achieve a non-dualistic mindset, then every Hindu will have a brain that is common with another Hindu. Achieving this is not a big task as it would just require removing all the false identities that we have come to be emotionally attached with. Advaita does not require Hindus to dilute or dissolve their selves or existing identities. It just requires them to understand that whatever their existing selves or identities are in their current state, they are only a tool or a means to achieve certain ends. This means merely awakening oneself to the non-dualistic mindset.

Once Hindus are able to access this non-dualistic mindset then they will be able to work towards rapid progress and expansion of Hinduness/Hindutva.

Hindu Unification through removal of dividing lines of thoughts, inner mental conflicts, awakening to what is already common in front of us. Non-dualistic Advaita as a road to achieving a unified Hindu brain.
