Krishna, God, the Supreme and Absolute Person, teaches us about the ideal attitude to adopt in the face of our suffering: Ephemeral joys and sorrows, like summers and winters, come and go. They are due only to the contact of the senses with matter, and we must learn to tolerate them without being affected by them.
He who is unaffected by neither joy nor sorrow, who remains serene and resolute in all circumstances, he is worthy of liberation (salvation).
We cannot escape suffering in this world; the only remedy is to tolerate, accept, and endure it. And he who manages not only to tolerate the miseries of this world, but also manages to remain calm and serene in the face of the joys and sorrows of this world, is worthy of liberation and will see his situation improve.
Anyone who is firmly determined to realize their spiritual self, and who can tolerate the onslaughts of both misfortune and good fortune, is ready to attain liberation. No obstacle can stop the being who truly desires to make their life perfect. We can make our lives perfect by learning to tolerate the difficulties of this life and, in the next, by returning to a world where suffering does not exist—the spiritual world.
Suffering is useful and necessary because, through the pain experienced, it allows us to understand what malicious thoughts, words, and actions generate, and thus to make the firm resolution never again to do evil in any form whatsoever, to anyone—humans, animals, or plants.
Suffering is useful and necessary because it allows us to reduce the mass of culpable acts accumulated during all our previous lives and to erase the sins inherent in these malicious, even criminal, acts.
Suffering is useful and necessary because it allows us to have a precise understanding of the pain felt by the person we harmed in our previous life, when we were indifferent to their cries. It also allows us to know that “what we have done will be done to us.”
Suffering is useful and necessary because it allows us to become aware of our malicious acts, to do penance, to repent, to ask for forgiveness, to turn to God, and to definitively respect and apply divine precepts, laws, and commandments.
