In the Bhagavad-Gita, Lord Krishna teaches equality and justice towards all living beings.

1. truly wise person sees all living beings with equal vision.

“The humble sages, by virtue of true knowledge, see with equal vision a learned and gentle brahmana, a cow, an elephant, a dog and a dog-eater [outcaste].” (Lord Krishna, Bhagavad-Gita 5.18)

2. To be situated on the spiritual platform, one has to conquer material life by seeing everything with equality.

“Those whose minds are established in sameness and equanimity have already conquered the conditions of birth and death. They are flawless like Brahman, and thus they are already situated in Brahman.” (Lord Krishna, Bhagavad-Gita 5.19)

3. A spiritually advanced person (a yogi), empathizes with all living beings.

“He is a perfect yogi who, by comparison to his own self, sees the true equality of all beings, in both their happiness and their distress, O Arjuna!” (Lord Krishna, Bhagavad-Gita 6.32)

4. One who realizes that God is in all beings is the true seer and he becomes qualified to enter the spiritual manifestation.

“One who sees the Supersoul accompanying the individual soul in all bodies, and who understands that neither the soul nor the Supersoul within the destructible body is ever destroyed, actually sees. One who sees the Supersoul equally present everywhere, in every living being, does not degrade himself by his mind. Thus, he approaches the transcendental destination. (Lord Krishna, Bhagavad-Gita 13.28-29)

5. One who is fixed on equality of everything becomes free from desires and is joyful in all situations. Such a person has attained the highest devotion to God.

“One who is thus transcendentally situated at once realizes the Supreme Brahman and becomes fully joyful. He never laments or desires to have anything. He is equally disposed toward every living entity. In that state he attains pure devotional service unto Me.” (Lord Krishna, Bhagavad-Gita 18.54)

6. Lord Krishna Himself sets a perfect example of equality and justice. He treats everyone fairly.

“I envy no one, nor am I partial to anyone. I am equal to all. But whoever renders service unto Me in devotion is a friend, is in Me, and I am also a friend to him.” (Lord Krishna, Bhagavad-Gita 9.29)

Conclusion

So long as people think of themselves as the body. They will remain in the bodily concept of life, which is full of desires, anxiety, anger, fighting, jealousy, and hatred. Those who realize that the living entity (the real us) is the eternal spiritual soul, such persons can transcend material life and attain the spiritual manifestation.
