paiya manusa janma, ye na sune gaura-guna,
hena janma tara vyartha haila
paiya amrtadhuni, piye visa-garta-pani,
janmiya se kene nahi maila
paiya manusa janma—anyone who has gotten the form of a human body; ye—who; na—does not; sune—hear; gaura-guna—the qualities of Lord Caitanya Mahaprabhu; hena janma—such a birth; tara—his; vyartha haila—becomes useless; paiya—getting the opportunity; amrtadhuni—of the river of nectar; piye—drinks; visa-garta-pani—water in a poison pit of material happiness; janmiya—taking birth as a human being; se—he; kene—why; nahi—did not; maila—die.
Anyone who attains a human body but does not take to the cult of Sri Caitanya Mahaprabhu is baffled in his opportunity. Amrtadhuni is a flowing river of the nectar of devotional service. If after getting a human body one drinks the water in a poison pit of material happiness instead of the water of such a river, it would be better for him not to have lived, but to have died long ago.
acaitanyam idam visvam yadi caitanyam isvaram
na viduh sarva-sastra-jna hy api bhramyanti te janah
caitanya-candre prakate yo dino dina eva sah
"A person who does not take advantage of the nectar of devotional service overflowing during the presence of Sri Caitanya Mahaprabhu's cult is certainly the poorest of the poor."
avatirne gaura-candre vistirne prema-sagare
suprakasita-ratnaughe yo dino dina eva sah
samstutah purusah pasuh
jatu nama gadagrajah
bile batorukrama-vikraman ye
na srnvatah karna-pute narasya
jihvasati dardurikeva suta
na copagayaty urugaya-gathah
jivan chavo bhagavatanghri-renum
na jatu martyo 'bhilabheta yas tu
sri-visnu-padya manujas tulasyah
svasan chavo yas tu na veda gandham
"A person who has no connection with Krsna consciousness may be a very great personality in so-called human society, but actually he is no better than a great animal. Such big animals are generally praised by other animals like dogs, hogs camels and asses. A person who does not lend his aural reception to hearing about the Supreme Personality of Godhead must be considered to have earholes like holes in a field. Although that person has a tongue, it is like the tongue of a frog, which unnecessarily creates a disturbance by croaking, inviting the snake of death. Similarly, a person who neither takes advantage of the dust of the lotus feet of great devotees nor smells the tulasi leaves offered to the lotus feet of the Lord must be considered dead even though he is supposedly working."
Similarly, the Srimad-Bhagavatam, Tenth Canto, Chapter One, verse 4, states:
puman virajyeta vina pasu-ghnat
"Who but the animal-killer or the killer of the soul will not care to hear glorification of the Supreme Personality of Godhead? Such glorification is enjoyed by persons liberated from the contamination of this material world."
Similarly, in the Third Canto, Chapter Twenty-three, verse 56, the Bhagavatam says, na tirtha-pada-sevayai jivann api mrto hi sah: "Although a person is apparently living, if he does not serve the lotus feet of great devotees he is to be considered a dead body."
