Śrīmad-Bhāgavatam
[Canto 1, Ch. 13]
there is eternal time, which is called  kāla  because it changes the shape of everything in the material world. Even if we are able to do something temporarily beneficial, time will see that the good project is frustrated in course of time. The only thing which is possible to be done is to get rid of the eternal time,  kāla , which is compared to  kāla-sarpa , or the cobra snake whose bite is always lethal. No one can be saved from the bite of a cobra. The best remedy for getting out of the clutches of the cobralike  kāla  or its integrity, the modes of nature, is  bhakti-yoga , as it is recommended in the  Bhagavad-gītā  (Bg. 14.26). The highest perfectional project of philanthropic activities is to engage everyone in the act of preaching  bhakti-yoga  all over the world because that alone can save the people from the control of  māyā  or the material nature represented by  kāla ,  karma  and  guṇa , as described above. The  Bhagavad-gītā  (Bg. 14.26) confirms this definitely.
TEXT 47

    फल्गुनि तत्र महतां जीवो जीवस्य जीवनम् ॥४७॥

ahastāni —those who are devoid of hands;  sa-hastānām —of those who are endowed with hands;  apadāni —those who are endowed with legs;  catuḥ-padām —of those who have four legs;  phalgūni —those who are weak;  tatra —there;  mahatām —of the powerful;  jīvaḥ —the living being;  jīvasya —of the living being;  jīvanam —subsistence.
TRANSLATION
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.
PURPORT
A systematic law of subsistence in the struggle for existence is there by the supreme will, and there is no escape for anyone by any amount of planning. The living beings who have come to the material world against the will of the Supreme Being are under the control of a supreme power called  māyā-śakti , the deputed agent of the Lord, and this  daivī māyā  is
