Ashtavakra Gita 3.10 -

The Sage is presenting a very high degree of spiritual vision. Though the body is formed and personal, the mind within, like the air we breathe, is formless and impersonal. In its vision, all bodies are equally its imprints within. So, the Knower sees his body just as he is looking at another’s.

Praise and ridicule others indulge in about him are just like those made about another person. People always relish praising someone and blaming another. Closely analysed, this is more a habit of theirs, than otherwise. The praisers rejoice in praising. So they pick up somebody for the purpose. So too, they revel in blaming some one. Both are their own wish and will, preferences. What does the Knower have to do in the whole process?

At best he can examine what they say, to find whether there is anything blameworthy in him as imputed. If there is, then he must feel grateful and strive to redress it, to get more enriched. Otherwise leave the subject for the blamers to deal with. Every time, the instance only deepens his clarity and steadiness. In fact, such dvandvas are necessary to purify and stabilize one’s mind. He should be happy that he has such an opportunity for self-enrichment.

The response in the Knower can be very enlightening and stabilizing. We have a number of unique subhāshitams (wise-sayings), which instil new vision, enhance inner expanse, making you more flexible and assimilative. The process is greatly enriching.

मन्निन्दया यदि जन: परितोषमेति
नन्वप्रयत्नसुलभोऽयमनुग्रहो मे।
लोके जना हि जनतापरितोषणाय
दुःखार्जितान्यपि धनानि परित्यजन्ति॥

If by blaming me, anyone finds delight, it is an effortless reward for me. In order to bring delight to others around, men spend a great deal of their hard-earned money. Here, without any expenditure, I am being the source of delight for others. It is a great blessing indeed!

In another subhashita, the subject is even more exultingly covered:

ददतु ददतु गालीं गालिवन्तो भवन्त:
वयमिह तदभावाद् गालिदानेऽप्यशक्ता:।
जगति विदितमेतद् दीयते विद्यमानं
न हि शशकविषाणं कोऽपि कस्मै ददाति॥

You are blaming me liberally, because you have ample stock of blame with you. But know that I do not have any stock of blame at all with me. So I do not respond to you. It is clearly known in the world, that one gives others only what he has. None gifts the horn of a hare to anyone. Because such a thing is not available at all.

Human mind, if flexible and assimilative, can receive practically anything from the world. While inputs are seemingly from others, their reception and effects are inner and one’s own mind’s creation. You have to assimilate only your own response to other’s blameful words, and not what they say. As all thoughts dissolve in the mind, these too will, even faster and more easily, if you strive well.
