The Lord clarifies that only those who have completely abandoned the path of sin and its consequences have access to the sublime service of love offered to the Lord. The entire set of Vedic ritual prescriptions (from the Vedas, the original sacred scriptures) is specifically designed to guide conditioned souls onto the path of piety, and by strictly adhering to the principles laid out for each group in society, one can acquire the qualities of truthfulness, mastery of the mind and senses, tolerance, and so on, and thus be raised to the level where it is possible to practice pure devotional service. Through this single spiritual vision, all material aspirations are fulfilled.
Krishna specifies in this regard: It is only through devotional service, and only in this way, that one can know Me as I truly am. And the being who, through such devotion, becomes fully conscious of My Person, can then enter My absolute realm.
It is only by serving Me with undivided love and devotion that one can know Me as I truly am, and likewise, truly see Me. Thus, and only thus, can one penetrate the mystery of My Person.
When the Lord was present on earth, those beings whose material desires were fulfilled simply by contemplating Him in truth were able to return with Him to His kingdom. But those who could not see Him as He is remained attached to their material desires and could not return to God's kingdom, their original abode. And when the Lord disappeared from all sight, He did so in His original, eternal form. He departed this world in His own fully spiritual body.
Krishna, God, the Supreme Person, appears only to relieve the abusive burden caused by demonic, ungodly, wicked, and unbelieving people. Once his task is complete, he simply disappears from the world's view.
Lord Krishna personally comes to this world to unveil his absolute spiritual amusements. He appears to draw us conditioned souls back to Him, so that we may return to our original abodes in the eternal spiritual realm.
What is the true cause of wars and cataclysms?
What provokes them and engenders the resulting suffering?
Those who flout divine laws and commandments fall under the laws of action and reaction, also called the laws of cause and effect, or karma, which compel everyone to suffer the consequences of their guilty thoughts, words, and deeds.
Thus, according to these laws, all thoughts, words, and actions, good or bad, will undoubtedly produce effects that will lead to positive or negative consequences, which will be felt in the next lifetime.
In truth, the suffering we endure today is the result of our guilty deeds committed in our previous lives. We ourselves are responsible for the suffering we endure.
Those who act in a self-interested way, for their own pleasure, who cling to the material world by developing materialism to excess, who reject Krishna, God, the Supreme Person, will experience at their death, various bodies according to their karma, because they will reincarnate and undergo births, deaths and sufferings of existence repeatedly.
