In this connection Caitanya Mahāprabhu related a story from Śrīla Madhvācārya's commentary on the Fifth Canto of Śrīmad-Bhāgavatam (5.5.10–13). This story involves the instructions of the astrologer Sarvajña to a poor man who came to him to have his future told. When Sarvajña saw the man's horoscope, he was astonished that the man was so poor, and he said to him, "Why are you so unhappy? From your horoscope I can see that you have a hidden treasure left to you by your father. However, the horoscope indicates that your father could not disclose this to you because he died in a foreign place. But now you can search out this treasure and be happy." This story is cited because the living entity is suffering due to his ignorance of the hidden treasure of his supreme father, Kṛṣṇa. That treasure is love of Godhead, and in every Vedic scripture the conditioned soul is advised to find it. As stated in the Bhagavad-gītā, although the conditioned soul is the son of the wealthiest personality—the Personality of Godhead—he does not realize it. Therefore the Vedic literature is given to him to help him search out his father and his paternal property.
The astrologer Sarvajña further advised the poor man: “Don’t dig on the southern side of your house to find the treasure, for if you do so you will be attacked by a poisonous wasp and will be baffled in your efforts to find the treasure. Search on the eastern side, where there is actual light, which is devotional service, or Kṛṣṇa consciousness. On the southern side there are Vedic rituals, on the western side there is mental speculation, and on the northern side there is meditational yoga.”
