40. In this endeavour there is no decrease or loss, and a little advancement on this path can save one from the most dangerous type of fear.
Significance:
The most dangerous type of fear is that one has to admit one is not God oneself. In the material world people like to be in control, but pople are neither the actor, nor the controller in the material world. To get rid of the comical but nevertheless strong fantasy one is in charge in the material world, which has all kinds of expressions and for which people have kinds of explanations, one has to quit false ego, quit identifying with the lala lands in the mind. Only false ego one can say goodbye to, not ego, since ego is eternal. Many people want to quit ego when they realise life in the material world is a most frustrating situation. But ego is eternal, one can’t leave ego. False ego is the source of ignorance and suffering, and actual ego is the source of knowledge, peace and joy.

41. Those who are on this path are resolute in purpose, and their aim is one. O beloved child of the Kurus, the intelligence of those who are irresolute is many branched, scattered all over the place. Therefore without any functionality and practically speaking invisible.
Significance:
When a person is irresolute he generally has all kinds of doubts. To have all kinds of doubts, and therefore to be indecisive, actually means one is very stubborn in doubting. Stubborn people cannot make any advancement in spiritual life, for they lack conviction and determination. When a person is convinced and therefore carries out the teachings of a bonafide spiritual teacher he will make spiritual advancement. Because of this his buddhi, his actual intelligence, gradually becomes more and more manifest. With it the person gradually leaves the mental plane, the plane of deeply rooted ignorance and suffering, the plane of all kinds of electrified motions. And more and more he comes to the level of genuine intelligence and actual quietness.

42-43. Men of small knowledge are very much attached to the flowery words of the Vedas, which recommend various fruitive activities for elevation to heavenly planets, resultant good birth, power, and so forth. Being desirous of sense gratification and opulent life, they say that there is nothing more than this.
Significance:
The Vedic scriptures carry hundreds and thousands of verses and mostly deal with life in the material world, the world of all things temporary. Many people are fruitive workers and God also gives facility to these people. Fruitive workers are not interested in total freedom of existence, they prefer to remain in illusion. They sometimes frivolously state something like: “Haha, I will go and practise spiritual life when I’m a pensioner”. But material life can change in such a dramatic way and on such very short notice that a person may be forced to leave the body when still being very young.

44. In the minds of those who are too attached to sense enjoyment and material opulence the resolute determination to get ones intelligence manifested does not take place.
Significance:
When a person refuses to engage his practical activities in reviving his lost relationship within the Absolute Truth, ones buddhi will remain in the spheres delusion and with it eternally unavailable. Making mental adjustments every other day, a tiresome and useless though popular activity for many, will not do the job.

45. The Vedas mainly deal with the subject of the three modes of material nature. Oh Arjuna, become transcendental to these modes and be free from all anxieties for safety and gain, and be established in the self.
Significance:
The three modes of material nature, the material universe, is a sound vibration. It is the remote control of God, which is very near to all. As long as one prefers material existence God provides the phantasmagoria. Bhagavad Gita 7.21 states: “I am in everyone's heart as the Supersoul. As soon as one desires some temporary form, I make his faith steady so that he can devote himself to that particular deity”. However, when a person is fortunate he quits the nonsense. So then there is no whining, no crying and no complaining anymore. Then there is simply reconnecting within the actual & ultimate reality and achieving total success in life.
