Bhagavad Gita – II – 70

The rivers and the ocean

Apuryamanam Achalapratishtam Samudram Apaha Pravishanti Yadvat|

Tadvat Kama Yam Pravishanti Sarve Sashantim Apnoti Na Kama Kami||

Just as the ocean remains steady even after all te waters merge into it, like a steady mountain, in the same way, the man in whom all objects of desires merge, remains steady. The one who runs after all objects of desire, does not experience any peace whatsoever. – SS.

Bhagavad Gita – II – 69

What is day for us is night for them

Ya Nisha Sarva Bhutanam Tasyam Jagarti Samyami|

Yasyam Jagrati Bhutani Sa Nisha Pashyato Munehe||

When the beings of the world are awake to the pleasures of the senses they are in darkness of the night towards the self. The one who is completely aware is wide awake to the reality that is present at all times. However, when the whole world is asleep to the reality, the wise one is awake. – SS.

Bhagavad Gita - II - 68

Senses drawn inward

Tasmad Yasya Mahabaho Nigrihitani Sarvashaha|
Indriyanindriyarthebhyaha Tasya Prajna Pratishtitha||

Having mentioned in the earlier verse about how the mind goes to where the senses go, Sri Krishna says that he is a man who has his intellect firmly rooted in the truth, who has all his senses drawn and is in full charge of them. - SS.

Bhagavad Gita - II - 67

As if pushed by the winds

Indriyanam Hi Charatam Yanmanonuvidheeyate|
Tadasya Harati Prajnam Vayurnavam Ivambhasi||

When the senses - eyes. ears. nose, taste and touch go in search of objects that they are attracted to - ears towards sounds that it likes to hear, taste towards objects of one's like, eyes to where it wants to see, nose to smells that please and touch to objects that are soft, hard or cozy, the mind helplessly follows in that direction as the winds push the ship around in an ocean. - SS

The Bhagavad Gita - II - 66

नास्ति बुद्धिरयुक्तस्य नाचायुक्तस्य भावना।
नचाभावयत: शंति: अशान्तस्य कुतः सुखं।।

 Where is joy when the intellect is unconnected

For the one who is not rooted in the truth, the Buddhi or intellect is non-functional. When the Buddhi does not function, there is no possibility of having a firm picture of the divine self, whether in a form or without it. The Buddhi is the one that gives a definite picture. In the place of the Buddhi, the mind rules. The mind as you know is never steady. It is always wavering with its innumerable thoughts. It means, such a person knows no peace. When there is no peace of mind, where can one expect to experience bliss?
The equation goes like this - an unconnected intellect cannot have a divine glimpse of the truth. It is replaced by the wavering mind. The mind is unsteady and hence knows no peace. When there is no peace, there is no experience of bliss too!

Bhagavad Gita - II - 65

Prasade Sarva Duhkhanam Hanirasyopa Jayate|
Prasanna Chetaso hyashu Buddhih Paryavatishthate||

In that state of divine blessedness, all sorrow is destroyed. In its place, there is a a cheerful and enthusiastic state of mind that surrounds the intellect and heart. Enthusiasm is the greatest religion. It is an offshoot of intense Shraddha and faith. Without enthusiasm, the intellect loses its fuel that makes it stand straight. When all the impurities of the mind that keep the intellect on shaky ground is gone, there is nothing else left for the mind to be steady and this steady mind is the state of a Sthitha Prajna.

Bhagavad Gita - II - 64

The Prasada Buddhi

Raga Dwesha Viyuktaistu Vishayan Indriyaischaran|
Atmavashyair Vidheyathma Prasadham Adhi Gacchati||

When the person who moves about in this world following the path of the sense organs, however is free from attachment and hatred, is rooted in the self alone, attains to that state of mind which is rooted in grace. For such a person, everything that comes to him in life - whether it is a person, a relationship, an event or a situation is the Prasada of the Lord. When we receive prasada at a temple or at a satsang, we are not expected to question the taste, ask for more or comment on the less sugar or more salt etc. We receive prasada as it is and just consume it, probably sharing with those who haven't received.

Likewise, for a person who neither seeks nor shuns, everything that happens is Ishwara Prasada. - Swahilya Shambhavi.
