Srimad Bhagavatam Canto 01, Chapter 04, Text 16

SB 1.4.16

paravara-jñah sa rsih
kalenavyakta-ramhasa
yuga-dharma-vyatikaram
praptam bhuvi yuge yuge
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The great sage Vyasadeva saw anomalies in the duties of the millennium. This happens on the earth in different ages, due to the unseen force of time.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The great sages like Vyasadeva are liberated souls, and therefore they can see clearly past and future. Thus he could see the future anomalies in the Kali age, and accordingly he made arrangement for the people in general so that they can execute a progressive life in this age, which is full of darkness. The people in general in this Age of Kali are too much interested in matter, which is temporary. Because of ignorance they are unable to evaluate the assets of life and be enlightened in spiritual knowledge.
