God has many, many  facilitating and functional forms , He also has responsive forms to particular circumstances , and of course, His glorious Lila pastimes forms . His original form is  the Supream personality of Godhead Lord Krishna , He is the original Supreme personality of Godhead . God is described  within the Vedas as being complete, more complete, and most complete, and this is reflected  in the way He reciprocates with His devotees . In Vrndavana, Krishna displays His most complete original form along with Srimati Radharani and all His family and various friends.  Srimati Radharani is the original Supreme Goddess of Fortune who  expands  Herself to bring unlimited blissful pastimes for the pleasure of Krishna who reciprocates accordingly.
The Srimad Bhagavatam and the Caitanya Caratamrita explain all these trancendental events ,  both of these works have been translated and commented on by Srila AC Bhaktivedanta Swami Prabhupada and are available to read in English as well as other Gaudia Vaisnava acaryas.

Schrödinger, the famous physicist, thought there was only one mind ……much akin to Sankaracarya and the impersonal school

In that sence its a fact that Annirudha , the portion of Visnu , is the total material mind , that the individual living beings are covered by  and utalise in materialism.   However, the original pure spiritual mind has its spiritual independence and individual capacity . The  full meaning of simultaneously and inconceivably one and difference is exhibited in a spiritual realm .
Srila Jiva Goswami says we should not overstate the oneness or the difference in any of the realms . Conditioned natures exhibited in this world mean a greater covering  of knowledge and an illusion of freedoms , one’s full potential is suppresed by our own attractions to an illusory energy.
