Lord Kṛṣṇa says that, "My dear Arjuna, we find so many species of life, eight, eight thousand, no, eight millions four hundred thousand, eight million four hundred thousands of species of life. All of them, they are My sons. I am the seed-giving father." He accepts that every living being, either man or beast or ant or bird, everyone, anywhere, they're all sons of God.
And they are suffering here. Manaḥ ṣaṣṭhānīndriyāṇi prakṛti-sthāni karṣati (BG 15.7). They have, somehow or other, they have come in contact with this material nature, and each and every one of these living entities, they are making, having a hard struggle for existence. But under the spell of the illusory energy, they are thinking we are happy. Although whole day and night, they are unhappy. Their desires are not fulfilled. They want something, but they are forced to accept something else. This is going on. This is called hard struggle for existence. Nobody's satisfied. There is always disruption. In this moment, I am your friend. Next moment, I am your enemy. This moment, I am your husband or wife. Next moment, no. Don't see my face. I'll not see your face. Divorce. So these things are going on. So this is called struggle. I am wanting something, but I am accept, I am forcefully being bound to accept something else. This is called struggle. So this is going on.
