Is ultimate samadhi necessary not-dualistic?

[Amrut]

Namaste.

1)Mind is just an instrument as well.

True. samadhi is beyond realms of mind and 5 senses. Hence it is inexpressible.

2)I think that all hindus do not consider them-self as their bodies.
For example,as gaudiya-vaishnava,I consider my-self an eternal spiritual soul and an infinitesimal parcel of God.

True. This is the belief. One confirms when one experiences the same.
