In truth, God does not want us to suffer, but because of our individualism, our unbridled desire to develop sensual pleasures, our desire to constantly strive for materialism, to increase our material wealth and consolidate our power, our desire to knowingly ignore the fact that our thoughts, words, and actions generate effects that, in turn, cause negative consequences that can ultimately cause suffering to others, and our disrespect for and failure to apply divine precepts and commandments, suffering is useful and necessary, because it allows us to regain our senses, to no longer act irresponsibly, and to modify our behavior by applying the scriptural prescriptions from the Vedas, the original holy scriptures.
It is through suffering that man erases his faults, reduces the number of accumulated sins, and becomes aware of the pain his sinful actions cause, leading him to resolve never to do it again.
The Lord concludes by saying: After having passed through all the conditions of hellish suffering and having experienced the lowest forms of animal life in the natural order, the spiritual being, having thus purged his faults, is reborn again in human form on this earth.
Illnesses of a spiritual nature.
In truth, human beings are subject to two types of illnesses. The first is material in nature, and the second, the main one, is spiritual in nature.
In reality, the cause of all illnesses is spiritual in origin. And the major cause is the forgetting of our loving relationship with Krishna, God, the Supreme Personality.
The material illnesses of the spirit soul are those transmitted by karma, that is, those that pass from the body the soul had in its previous life to the one in which it was reincarnated.
The material body is actually the prison of the spirit soul. We have forgotten this, but the fetus in the mother's womb, and then at birth, the being suffers. The body is the source of the suffering of the incarnate spiritual being. The illness that affected our body in our last life, due to our karma and because we have not erased it, will move and reappear in the body we will have in our next existence. We will find ourselves in a new body affected by the same illness.
This is why we often see babies born with serious illnesses, partially paralyzed or even totally degenerative...
God alone controls everything for us. We are all under His tutelage. Even the material body in which the soul is reincarnated does not belong to Him, because it is the property of Lord Krishna. We come into this world with nothing, and it is empty-handed that we will leave it when the time comes. Everything belongs to God. He is not responsible for the misfortunes and suffering we endure.
In reality, we ourselves are responsible for the illnesses, misfortunes, and suffering we endure. The more wicked we are, the more we express through thought, word, and deed hatred, racism, indifference, and coldness of heart toward those who are different from us, the more the mass of our evil deeds increases due to the clouding of our minds, and the more we will be led to suffer in our present life, but especially in our future life.
