All these activities helped him attain the perfect stage of life which defeats all dexterities of material science.
It is therefore important for all human beings to adopt these principles of spiritual realization for the perfection of life. A human being's only obligation is spiritual realization. Unfortunately, in modern civilization, human society is too busy in discharging national duties. Actually, national duties, social duties and humanitarian duties are obligatory only to those who are bereft of spiritual duties. As soon as a man takes his birth on this earth, not only does he have national, social and humanitarian obligations, but he also has obligations to the demigods who supply air, light, water, etc. He also has obligations to the great sages who have left behind them vast treasure-houses of knowledge to guide him through life. He has obligations to all kinds of living beings, to his forefathers, family members and so forth and so on.
