65. In such a satisfied state of consciousness one doesn’t suffer anymore and ones intelligence is an established fact.
Significance:
It is interesting to note many people in Kali yuga are not willing to quit their suffering. They refuse to have their mea culpa, mea culpa, mea maxima culpa, and engage in the solution, engage in yoga. By yoga we don’t mean having some breathing exercises and having some gymnastics for two or three times per week for two or three hours. We mean the 24/7 engagement of reconnecting within the Supreme. That generally takes some time to reach, like a couple of months, a couple of years, or a couple of bodies.

66. One who is not connected with the Supreme in Krishna consciousness can have neither transcendental, actual intelligence, nor a peaceful mind. And how can’t there be any happiness without peace?
Significance:
Quite a few people make a show of their so called happiness. When asking them “how are you doing?” they will react with “GREAT, WONDERFUL!” and give you a big smile, while in actuality they are fearful, angry, depressed or even thinking of committing suicide, which is impossible, since the true self is eternal.

67. As a strong wind sweeps away a boat on the water, even one of the roaming senses on which the mind focuses can carry away a man’s intelligence.
Significance:
Worhipping the idols in the mind is the activity of a person with deluded consciousness. For such a person it’s impossible to realise Krishna, the Unlimitedly Playful and Naughty One.

68. Therefore, O mighty Skull Cracker & Catapulter of Corpses, one whose senses are restrained from their objects is certainly of steady intelligence.
Significance:
The sense perceptions of hearing, seeing, touching, smelling and tasting can only be restrained when one has sense perception in actual knowledge. Otherwise these sense perceptions are in a toxic mental cocktail dominated by mirages like unlimited desires, disappointment, superficial success, performance anxiety, duplicity, arrogance, envy etc. etc.. In that way the realm of eternity remains an unknown world for the conditioned soul.

69. What is night for all beings is the time of awakening for the self-controlled, and the time of awakening for all beings is night for the introspectve sage.
Significance:
These beings, known as “bhutani” in Sanskrit, are all things temporary. The individual spirit soul is eternal and is eternal integrated part of the Supreme Being, God. All things temporary are illusory, and reside in the mind. The introspective sage is not influenced by them. In Bhagavad-Gita 4.35 Krishna states: “Having obtained eternal knowledge a person does not fall into illusion again for he realises that all beings are but of the Supreme, or in other words, that they are Mine, Vishnu”.  So as we render unto Caecar what is his, that is all out total war because that is what you have with politicians, the enlightened souls leave Vishnu, the descendance of Krishna who supplies all nonsense, what is His. “Vishnu, you can keep your nonsense, I only want Krishna, the one with the one head, the two arms and the two legs”, is the conclusion of the lover of the Lord.
