The wise soul remains undisturbed by body changes, understanding the spirit's eternal nature transcends material existence.Listen — Srila Prabhupada Uvaca
Prabhupāda: dehino 'smin yathā dehe kaumāraṃ yauvanaṃ jarā tathā dehāntara-prāptir dhīras tatra na muhyati [Bg 2.13] [As the embodied soul continually passes, in this body, from boyhood to youth to old age, the soul similarly passes into another body at death. The self-realized soul is not bewildered by such a change.] This is thirteenth śloka. You can open it. The Sanskrit word is, dehino 'smin yathā dehe kaumāraṃ yauvanaṃ jarā tathā dehāntara-prāptir dhīras tatra na muhyati [Bg 2.13]
Student: "Just as boyhood, youth and old age are attributed to the soul through this body, he, the soul, obtains another body. The wise man does not get deluded about this." Prabhupāda: Yes. Now, this wise man, the word, Sanskrit word, is dhīra. Dhīra means that one who is undisturbed in mind.
And our disturbance of the mind is due to our ignorance. Suppose I want to go somewhere. Now I am in the station. And actually, it so happened when I came to New York first from India.
I was to be dispatched to Butler by the bus station. But I was a new man; I did not know the rules and regulation. Of course, somebody was guiding me. Still, I was very much in disturbed condition, how to get on the bus, how to get the ticket, how...
All these things. So disturbance of mind is due to our ignorance. [someone enters] Yes. Come in. [chuckles] Yes.
So disturbance of mind is due to our ignorance. So here, a very nice word. [aside:] You can come here. All right. Here a very nice word is used: dhīra. Dhīra.
Dhīra means undisturbed. Undisturbed. So this we should, we should carefully note, that our mind in the material condition is always disturbed, always disturbed. And this is due to our unfavorable condition. Because we are actually spirit in identity, and we have been put into material conditions.
