“Everyone in the material life, in all species and varieties of life, is full of anxieties, either by breaking or without breaking the laws of nature. Liberation, or mukti, means getting relief from these constant anxieties. This is possible only when the anxiety is changed to the devotional service of the Lord.” (Shrila Prabhupada, Shrimad Bhagavatam, 1.12.28 Purport)
