An intelligent man should utilize good opportunities. The first opportunity is the human form of life, and the second opportunity is to take birth in a suitable family where there is cultivation of spiritual knowledge; this is rarely obtained. The greatest opportunity is to have the association of a saintly person. Devahuti was conscious that she was born as the daughter of an emperor. She was sufficiently educated and cultured, and at last she got Kardama Muni, a saintly person and a great yogi, as her husband. Still, if she did not get liberation from the entanglement of material energy, then certainly she would be cheated by the insurmountable illusory energy. Actually, the illusory, material energy is cheating everyone. People do not know what they are doing when they worship the material energy in the form of goddess Kali or Durga for material boons. They ask, Mother, give me great riches, give me a good wife, give me fame, give me victory. But such devotees of the goddess Maya, or Durga, do not know that they are being cheated by that goddess. Material achievement is actually no achievement because as soon as one is illusioned by the material gifts, he becomes more and more entangled, and there is no question of liberation. One should be intelligent enough to know how to utilize material assets for the purpose of spiritual realization. That is called karma-yoga or jnana-yoga. Whatever we have we should use as service to the Supreme Person. It is advised in Bhagavad-gita sva-karmana tam abhyarcya: one should try to worship the Supreme Personality of Godhead by ones assets. There are many forms of service to the Supreme Lord, and anyone can render service unto Him according to the best of his ability.
