In Bhagavad-Gita it is mentioned that transcendental knowledge or, the science of relationship of an individual soul with the supreme was first given to Vivasvan (The demigod presiding over the Sun planet) about 120 million years ago. Vivasvan then gave this knowledge to Vaivasvata Manu, and he in turn gave it to Iksvaku, who bought the knowledge down to earth. Iksvaku belongs to a kingly order known as Raghu dynasty in which Lord Ramacandra appeared.
An important point to understand from this is that knowledge of Bhagavad-Gita was generally meant for kings and leaders so that they could rule the kingdom with spiritual conceptions and considerations of life and guide the citizens to connect with the Supreme Lord. Today, unfortunately the situation is completely opposite. Modern leaders who have no scruple are occupying political posts without transcendental knowledge, and this is resulting into all kinds of problems. There is so much sectarianism and lack of cooperation everywhere. Even among personal relationships we find so much sectarianism. There is no cooperation among countries, friends, families, religion and so on. Even husband-wife relationships are filled with all kinds of quarrels. The root cause of all this is people are working with material conceptions of life.
Therefore in order to avoid the situation as we face today, it was crucial for kings in Vedic times to be thoroughly educated in the science of Bhagavad-Gita so that they could effectively rule and guide the different members of the society to achieve the ultimate goal of life. Unless we see things with spiritual conceptions, our vision is certainly going to be defective.
There is a great need for the leaders to be educated in the science of Bhagavad-Gita if at all they want to bring about sanity in this world.
