The human society to which Lord Krishna refers is that which is progressing towards spiritual realization. True progress is that which leads people to spiritual upliftment, spiritual realization and consciousness of Krishna, God, the Supreme Person.

The wise scholars then strive to advance the spiritual cause, and the administrators, the kings who rule under the authority of God, have the task of governing the nation and ensuring that citizens have at their disposal all the facilities required for spiritual fulfilment.

The institution relating to the four divisions or social classes was conceived and created by God. Now, nothing created by the Lord can be destroyed or erased. Social classes will continue to exist, whether in their original form or in the current, degraded form, but because they were created by Krishna, God, the Supreme Person, nothing can annihilate them.

When these different groups are organized in such a way as to cooperate with each other according to the Vedic principles, the Vedas, the original holy scriptures, all humanity, including men, animals and plants, experiences peace and spiritual progress.

But when envy, covetousness, greed, hatred, anger, discrimination, disorder and mutual distrust appear between these social classes, then everything deteriorates and a deplorable situation results. At present, the whole world is in this deplorable state for having given citizenship to so many diverted interests of materialistic origin where the pleasure of the senses is the strain.

This state of affairs results from the degradation of the four social classes and the four spiritual orders. Today no one respects the social class to which they belong, out of pride and the pursuit of profit. It is now common to see beings coveting a superior position without having the required skills, nor the knowledge, the moral, intellectual and spiritual level that are required.

This is why God requires that we do not change activities, or that we do not decide to carry out the duties which fall to another competent person, even if we can carry out it perfectly, but to remain in our natural position, in the social class to which we belong, in order to fulfill our own duties. To want to fulfill the duty of another is to open the door to degradation and to sin.

The Lord said:“It is better to do one’s duty, even if it is imperfectly, than to do the duty of another, even to do it perfectly. By the fulfilment of the prescribed duties, which his nature assigns to each one, one never incurs sin”.
