Ordinarily, when we give up these body, we quit this body, we have to accept another body. Vāsāṁsi jīrṇāni yathā vihāya (BG 2.22). We have discussed this point that we living entities, our life is going on simply by changing dresses from one body to another, transgression (transmigration) of the soul, according to our work. So this, this body is dress. Therefore I have got an actual body.
Just like at the present moment we think, "This material body is my actual body, and there is dress, shirt and coat. The shirt and coat is superficial to this actual body." But here in the Bhagavad-gītā you'll find that we have got our real, spiritual body, separate from the material covering. And as we give up old garments, old dress, and take up another new dress, another new garment, similarly, we give up this body, material body, when it is old enough, when it cannot be used or . . . then we give it up, and we take another body. And this change of body is going on every moment and every second. This point also we have discussed.
