SB 5.18.33

yasminn asankhyeya-visesa-nama-
 rupakrtau kavibhih kalpiteyam
sankhya yaya tattva-drsapaniyate
 tasmai namah sankhya-nidarsanaya te iti
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O my Lord, Your name, form and bodily features are expanded in countless forms. No one can determine exactly how many forms exist, yet You Yourself, in Your incarnation as the learned scholar Kapiladeva, have analyzed the cosmic manifestation as containing twenty-four elements. Therefore if one is interested in Sankhya philosophy, by which one can enumerate the different truths, he must hear it from You. Unfortunately, nondevotees simply count the different elements and remain ignorant of Your actual form. I offer my respectful obeisances unto You.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Philosophers and scientists have been trying to study the entire cosmic situation and have been theorizing and calculating in different ways for millions and millions of years. However, the speculative research work of a so-called scientist or philosopher is always interrupted when he dies, and the laws of nature go on without regard for his work.
 
For billions of years changes take place in the material creation, until at last the whole universe is dissolved and remains in an unmanifested state. Constant change and destruction (bhutva bhutva praliyate) is perpetually going on in nature, yet the material scientists want to study natural laws without knowing the Supreme Personality of Godhead, who is the background of nature. As Krsna states in Bhagavad-gita (9.10):
 
mayadhyaksena prakrtih
 suyate sa-caracaram
hetunanena kaunteya
 jagad viparivartate
 
“This material nature is working under My direction, O son of Kunti, and it is producing all moving and unmoving beings. By its rule this manifestation is created and annihilated again and again.”
 
Now the material creation is manifest, eventually it will be annihilated and remain for many millions of years in a dormant state, and finally it will again be created. This is the law of nature.
