मघवन्मर्त्यं वा इदं शरीरमात्तं मृ-त्युना तदस्यामृतस्याशरीरस्यात्मनोऽधि-ष्ठानमात्तो वै सशरीरः प्रियाप्रियाभ्यांन वै सशरीरस्य सतः प्रियाप्रिययोरपह-तिरस्त्यशरीरं वाव सन्तं न प्रियाप्रियेस्पृशतः ॥ १ ॥
In plain words
Maghavan, this physical body is mortal, held firmly in the grip of death. Yet it serves as the temporary dwelling place of the true Self, which is immortal and bodiless. As long as one identifies with the body, one remains at the mercy of pleasure and pain; there is no escaping them while embodied. But when a person rests as the bodiless Self, pleasure and pain can no longer touch them.
Close to the Sanskrit
O Maghavan, mortal indeed is this body seized by death. That is the abode of this immortal, bodiless Self. The embodied one is indeed seized by the pleasant and the unpleasant. There is not indeed the removal of pleasure and pain for one who is embodied. But pleasure and pain do not touch him who is established as bodiless.
