Punishment and Reward of Kali

also it is confirmed (Bg. 6.5) that by one's mind, freed from material affection, one can deliver himself from the sufferings of material pangs. So one should not entangle oneself in matter by the mind's material affections. Thus one's own mind is one's friend or enemy in one's material happiness and distress.
Atheistic materialistic Sāṅkhyaites conclude that material nature is the cause of all causes. According to them, combinations of material elements are the causes of material happiness and distress, and disintegration of matter is the cause of freedom from all material pangs. Gautama and Kaṇāda find out that the atomic combination is the cause of everything, and impersonalists like Aṣṭāvarkra discover that the spiritual effulgence of Brahman is the cause of all causes. But in the  Bhagavad-gītā  the Lord Himself declares that He is the source of impersonal Brahman also, and therefore He, the Personality of Godhead, is the ultimate cause of all causes. It is also confirmed in the  Brahma-saṁhitā  that Lord Kṛṣṇa is the ultimate cause of all causes.

अप्रतर्क्यादनिर्देश्यादिति केष्वपि निश्चयः । अत्रानुरूपं राजर्षे विमृश स्वमनीषया ॥२०॥
apratarkyād anirdeśyād   iti keṣv api niścayaḥ   atrānurūpaṁ rājarṣe   vimṛśa sva-manīṣayā
apratarkyāt —beyond the power of reasoning;  anirdeśyāt —beyond the power of thinking;  iti —thus;  keṣu —someone;  api —also;  niścayaḥ —definitely concluded;  atra —herein;  anurūpaṁ —which of them is right;  rājarṣe —O sage amongst the kings;  vimṛśa —judge yourself;  sva —by your own;  manīṣayā —power of intelligence.
TRANSLATION
There are also some thinkers who believe that no one can ascertain the cause of distress by argumentation, nor can one know it by imagination, nor can it be expressed by words. O sage amongst kings, judge for yourself by thinking over all this with your own intelligence.
