The only possibility then is to search for the hidden treasure on the eastern side by the process of devotional service in full Kṛṣṇa consciousness. Indeed, that process of devotional service is the perpetual hidden treasure, and when one attains to it, he becomes perpetually rich. One who is poor in devotional service to Kṛṣṇa is always in need of material gain. Sometimes he suffers the bites of poisonous creatures, and sometimes he is baffled; sometimes he follows the philosophy of monism and thereby loses his identity, and sometimes he is swallowed by a large serpent. It is only by abandoning all this and becoming fixed in Kṛṣṇa consciousness, devotional service to the Lord, that one can actually achieve the perfection of life.
