What human life is meant for

Narottama dasa Thakura, a great devotee and acarya of the Gaudiya Vaisnava
sect, has sung: "My Lord, I have simply wasted my life. Having obtained the
human body, I have neglected to worship Your Lordship, and therefore I have
willingly drunk poison." In other words, the human body is especially meant
for cultivating knowledge of devotional service to the Lord, without which
life becomes full of anxieties and miserable conditions.
