To put an end to this and to live a happy life, it is enough to love God, to obey Him, to serve Him with love and devotion and to love all living beings, human, animal and vegetable without exception.
God alone controls everything for us. We are all under His tutelage. Even the material body in which the soul has been reincarnated does not belong to Him, as it is the property of Lord Krishna. We come to this world with nothing, and it is with empty hands that we will leave it when the time comes. Everything belongs to God.
In reality, the cause of all diseases is spiritual. And the major cause is the forgetfulness of our loving relationship with Krishna, God, the Supreme Person.
The soul that loses contact with God, forgets its own spiritual identity and engages in innumerable material activities that entangle it in a web of karma. This karma causes suffering, and instead of turning to God to alleviate its pain, the incarnated spiritual being seeks material solutions which unfortunately lead to further karmic reactions, and thus further suffering.
In the course of innumerable existences, incarnated spiritual beings have accumulated, through their thoughts, words and actions, a large mass of prejudices, guilty acts or sins which oblige them, and today suffer the resulting misfortunes and suffering. Therefore, it is through pain or suffering suffered and felt, that we diminish and erase our faults.
Suffering is useful and necessary.
It is the acts committed in the past or even the previous life of a being, which determine the conditions of his next birth or reincarnation, and existence. The suffering linked to culpable acts has a double origin: the acts themselves, but also those committed during previous lives.
The origin of sinful acts is most often ignorance. But the fact of not knowing that an act is guilty does not allow one to avoid, if one commits it, its undesirable consequences, which give rise to other guilty acts.
On the other hand, a distinction is made between two kinds of faults: those that are “mature”, so to speak, and those that are not yet mature. By “mature” faults we mean those whose consequences we are currently suffering. The others are those which, although numerous, have accumulated in us and have not yet produced their fruits of suffering.
The man who commits a crime may not be caught immediately and condemned, but sooner or later he will be. Likewise, we will have to suffer for some of our faults in the future, just as we suffer today for others that have “come to maturity”.
