B.G 2.22
वासांसि जीर्णानि यथा विहाय नवानि गृह्णाति नरोऽपराणि। तथा शरीराणि विहाय जीर्णान्यन्यानि संयाति नवानि देही ॥ २-२२॥
Just as a person accepts new garments discarding worn-out clothes, the embodied living being discarding worn-out bodies enters new ones.
Gīta Bhāshya 2.22
Discriminative and experiential knowledge of distinguishing between the body and the Ātmān is imparted.
देहात्मविवेकानुभवार्थं दृष्टान्तमाह– 'वासांसि' इति ॥ २२ ॥
To impart discriminative and experiential knowledge of distinguishing between the body and the Ātmān, a metaphor is provided in the above 'vāsāṁsi' verse.
Gīta Tātparya 2.22
The union and separation of the body for a living being are essentially birth and death, and therefore, they are not the cause of sorrow.
जीवस्यापि शरीरसंयोगवियोगावेव जनिमृती यतः ततो न दुःखकारणमित्याह। वासांसीति ॥ २२ ॥
The union and separation of the body for a living being are essentially birth and death, and therefore, they are not the cause of sorrow. Hence the 'vāsāṁsīti' verse.
