Śrīmad-Bhāgavatam
[Canto 9, Ch. 13]
ahastāni sahastānām apadāni catuṣ-padām phalgūni tatra mahatāṁ jīvo jīvasya jīvanam
“Those who are devoid of hands are prey for those who have hands; those devoid of legs are prey for the four-legged. The weak are the subsistence of the strong, and the general rule holds that one living being is food for another.” ( Bhāg.  1.13.47) The Supreme Personality of Godhead has created the material world in such a way that one living entity is food for another. Thus there is a struggle for existence, but although we speak of survival of the fittest, no one can escape death without becoming a devotee of the Lord.  Hariṁ vinā naiva sṛtṁ taranti : one cannot escape the cycle of birth and death without becoming a devotee. This is also confirmed in  Bhagavad-gītā  (9.3).  Aprāpya māṁ nivartante mṛtyu-saṁsāra-vartmani . One who does not attain shelter at the lotus feet of Kṛṣṇa must certainly wander up and down within the cycle of birth and death.
