Gan Eden is higher than the worlds

Gan Eden is higher than worlds, for the soil of Gan Eden is the spiritual dimension that is within the physicality of the world.

Chassidic Discourse of the Lubavitcher Rebbe, Pinchas 5711

Garment of the Soul

The body of the person, although it is only a garment for the soul, [nonetheless] it is unified with the soul, which is not the case with the garments which are separate from the person (also separate from the body of the person)...The intellect and emotional attributes are the "body" of the soul and thought, speech and action are the "garments".

Lubavitcher Rebbe, V'Nacha Alav 5714
