Original sin is the sin committed by spiritual beings while still in the spiritual world, by which they disobeyed God.
Disobedience to God includes refusing to serve Him, to recognize His supremacy, His authority, and all that exists as His exclusive property.
Furthermore, they began to envy God, thus seeking to usurp His supreme position, and to believe themselves to be the Sovereign Being Himself. It was for them that Lord Krishna, in His kindness, created the material universe after expelling them from the spiritual world.
What is the secret of spiritual success?
Indeed, all those who surrender completely to the Lord instantly receive the protection of the Supreme Personality of Godhead, Krishna, who will shield them from all perils.
To one who becomes a pure devotee of Krishna, God, the Supreme Personality of Godhead, and surrenders himself to Him, the Lord promises a perfect spiritual existence, which will entitle him to serve Him with absolute spiritual love. The Lord does not readily grant anyone the right to serve Him.
All those who love God, who delight in obeying Him, in doing His divine will, in serving Him with love and devotion, and who unwaveringly walk in His sublime path, remain peaceful, whatever good or bad situations they encounter. They accept the sufferings inflicted on them with calm and serenity, knowing that God can thus test their resolve to remain faithful to Him.
This is the secret of spiritual success, superior to material success, for it leads directly to God, in His infinite and absolute realm of knowledge, bliss, and eternity, and allows only the devotees of the Lord to see Him face to face forever.
The Lord God says: Only through devotional service, and thus alone, can one know Me as I am. And the being who, through such devotion, becomes fully aware of My Person, can then enter My absolute kingdom. Thus, and thus alone, can one penetrate the mystery of My Person. I reveal to you here the most secret of knowledge.
What is true knowledge?
True knowledge is the ability to distinguish the spiritual from the material.
The academic knowledge acquired in universities only touches on dense matter and can in no way be accepted as true knowledge, especially since it ends with death. Indeed, current material education remains incomplete, as it sheds no light on the spiritual, the soul, and existential truth. It stops at the material elements and the needs of the body.
Spiritual knowledge is superior to material knowledge because it is eternal and provides exclusive information relating to God and absolute truth.
