Lord Viṣṇu advised King Pṛthu that everyone should follow the principles of varṇāśrama-dharma; then, in whatever capacity one remains within this material world, his salvation is guaranteed after death. In this age, however, since the system of varṇāśrama-dharma is topsy-turvy, it is very difficult to strictly follow all the principles. The only method for becoming perfect in life is to develop Kṛṣṇa consciousness. As varṇāśrama-dharma is executed from different positions by different men, so the Kṛṣṇa consciousness principles can be followed by everyone in every part of the world.
There is a specific purpose in mentioning herein that one should follow the dvijāgryas, the most prominent brāhmaṇas, like Parāśara and Manu. These great sages have already given us instructions on how to live according to the principles of varṇāśrama-dharma. Similarly, Sanātana Gosvāmī and Rūpa Gosvāmī have given us rules and regulations for becoming pure devotees of the Lord. It is essential, therefore, to follow the instructions of the ācāryas in the paramparā system, who have received the knowledge as passed down from spiritual master to disciple. In this way, although living in our material condition of life, we can get out of the entanglement of material contamination without leaving our positions. Lord Caitanya Mahāprabhu advises, therefore, that one does not have to change his position. One simply has to hear from the perfect source (this is called paramparā) and follow the principles for practical application in life; thus one can attain the highest perfection of life—liberation—and go back home, back to Godhead. In other words, the change required is a change in consciousness, not in the body. Unfortunately, in this fallen age, people are concerned with the body, not with the soul. They have invented so many "isms" pertaining to the body only, not to the soul.
In the modern age of democracy there are so many government representatives voting for legislation. Every day they bring out a new law. But because these laws are only mental concoctions manufactured by inexperienced conditioned souls, they cannot give relief to human society. Formerly, although the kings were autocrats, they strictly followed the principles laid down by great sages and saintly persons. There were no mistakes in ruling over the country, and everything went perfectly. The citizens were completely pious, the king levied taxes legitimately, and therefore the situation was very happy. At the present moment the so-called executive heads are more or less selected from materially ambitious persons who simply look after their own personal interests; they have no knowledge of the śāstras. In other words, the executive heads are fools and rascals in the strict sense of the terms, and the people in general are śūdras. This combination of fools and rascals and śūdras cannot bring about peace and prosperity in this world. Therefore we find periodic upheavals in society in the forms of battles, communal riots and fratricidal quarrels. Under these circumstances, not only are the leaders unable to lead the people toward liberation, but they cannot even give them peace of mind. In Bhagavad-gītā it is stated that anyone who lives on concocted ideas, without reference to the śāstras, never becomes successful and does not attain happiness or liberation after death.
