Every man should so lead his life that no pain is caused by him to any living thing. That is his supreme duty. Also, it is the prime duty of every one, who has had the chance of this human birth, to spare a part of his energies occasionally for prayer, repetition of the Lord's Name, meditation etc., and must devote himself to Living with Truth, Rightfulness, Peacefulness and to good works which are of service to others. One must be as afraid of doing acts that are harmful to others or deeds that are sinful, as one is afraid to touch fire or disturb a cobra. One must have as much attachment and as much steadfastness in carrying out good works, in making others happy, and in worshipping the Lord as he now has in accumulating gold and riches. This is the Dharma of Man. It is to strengthen this type of goodness that the Lord incarnates Himself in human form. But, the question may arise, how can a non-existent thing be strengthened and developed? Indeed, these qualities are not non-existent; they are there in man! When these existing qualities decline and wither, the Lord comes with the purpose of promoting them and bringing about the decline of the forces that work in the oposite direction. It is to make clear this purpose that Sri Krishna, in the Dwapara Yuga, while teaching Arjuna, said:

Parithraanaaya saaddunaam
Vinaasaaya cha dushkrithaam
Dharmasamsthaapanaarthaaya
Sambhavaami yuge yuge.

That is to say, all incarnations of the Lord are for the protection and promotion of Sadhus. This word, Sadhu, does not refer to any single religion, caste, or familiy or stage of life, or community or even any single species, like the human! It refers to all religions, all stages of life, all races, and all creatures. The Lord has revealed in the Gita His Universal Mind. It is because of this universal message that the Gita has become so essential and so famous. Why! Sri Krishna Himself has declared in plenty of situations and places that He is the dutiful servant of His devotees. An example of this is His accepting to be the Charioteer of Arjuna.

If the culture of the ordinary man himself results in such elevation, each one can judge for himself how much more purified and holy will be the character of those who are engaged in spiritual exercises and the incessant contemplation of God! For both these types of people, the quality of the character is the important criterion.
