In this iron age,people are also iron hearted. One's ability to make the most of sense enjoyment is considered advanced civilization now. Truth is looked down upon,but Word jugglery which covers the truth is appreciated.Religious principles are considered obselete&only meant for old timers. What a pity? No one knows what is good for their own self. All have become mad men addicted to the abominable Habits of nasty lust,greed,pride,envy,anger,madness. These habits have

brought only self-destruction and destruction to those around all the time in the past,present and in future as well. This is an age of addiction. We are getting addicted to unwanted things even without our knowledge.

The same activities dancing,singing,sporting which when performed in clubs would otherwise bind us in the cycle of birth&death would liberate us when performed in front of Krishna in His temple for His pleasure. What's the difficulty? The result is twofold.We revive our lost Love for God. Other thing is We get released from the clutches of material energy simultaneously without even endeavoring for it separately.

The senses are like venomous serpents which need a better engagement like a snake charmer charming the snakes. The charm of the bluish boy standing on the banks of the river Yamuna alone can keep the senses intoxicated&free from the poison of the iron age. 

It's actually the same material elements transformed into poison because of the enviousness of snake. The same material elements transformed to different ones by the consciousness of the living entity. Food is converted to blood in the process of digestion, the body of a man automatically converts his blood to semen by his thinking of a woman, a mother her blood to milk to feed the baby. All this is acintya-inconceivable. The nails, hair that are growing are also inconceivable to us.

In the actual sense,we are simply observers and only choice makers with what is provided to us by nature. Even the evacuation which is our normal day to day activity is controlled by a demigod. 

" Everyone is forced to act helplessly according to the qualities he has acquired from the modes of material nature; therefore no one can refrain from doing something, not even for a moment"- BG # 3.5

(Purport to BG#13.3 begins)  

"One who studies the subject matter of the field of activity and the knower of the field very minutely, in terms of this Bhagavad-gītā, can attain to knowledge.

The Lord says, "I am the knower of the field of activities in every individual body." The individual may be the knower of his own body, but he is not in knowledge of other bodies. The Supreme Personality of Godhead, who is present as the Supersoul in all bodies, knows everything about all bodies. He knows all the different bodies of all the various species of life. A citizen may know everything about his patch of land, but the king knows not only his palace but all the properties possessed by the individual citizens. Similarly, one may be the proprietor of the body individually, but the Supreme Lord is the proprietor of all bodies. The king is the original proprietor of the kingdom, and the citizen is the secondary proprietor. Similarly, the Supreme Lord is the supreme proprietor of all bodies.

The body consists of the senses. The Supreme Lord is Hṛṣīkeśa, Which means "the controller of the senses." He is the original controller of the senses, just as the king is the original controller of all the activities of the state; the citizens are secondary controllers. The Lord says, "I am also the knower." This means that He is the superknower; the individual soul knows only his particular body. In the Vedic literature, it is stated as follows:

kṣetrāṇi hi śarīrāṇi

bījaḿ cāpi śubhāśubhe

tāni vetti sa yogātmā

tataḥ kṣetra-jña ucyate

This body is called the kṣetra, and within it dwells the owner of the body and the Supreme Lord, who knows both the body and the owner of the body. Therefore He is called the knower of all fields. The distinction between the field of activities, the knower of activities, and the supreme knower of activities is described as follows. Perfect knowledge of the constitution of the body, the constitution of the individual soul, and the constitution of the Supersoul is known in terms of Vedic literature as jñāna. That is the opinion of Kṛṣṇa. To understand both the soul and the Supersoul as one yet distinct is knowledge. One who does not understand the field of activity and the knower of activity is not in perfect knowledge. One has to understand the position of prakṛti (nature), puruṣa (the enjoyer of nature) and īśvara (the knower who dominates or controls nature and the individual soul). One should not confuse the three in their different capacities. One should not confuse the painter, the painting and the easel. This material world, which is the field of activities, is nature, and the enjoyer of nature is the living entity, and above them both is the supreme controller, the Personality of Godhead. It is stated in the Vedic language (in the Śvetāśvatara Upaniṣad 1.12), bhoktā bhogyaḿ preritāraḿ ca matvā/ sarvaḿ proktaḿ tri vidham-brahmam etat. There are three Brahman conceptions: prakṛti is Brahman as the field of activities, and the jīva (individual soul) is also Brahman and is trying to control material nature, and the controller of both of them is also Brahman, but He is the factual controller" (Purport to BG#13.3 ends)  

Only a pure devotee of Krishna can completely understand this knowledge which differentiates the material elements-jadam from the Spirit-cetanam,conscious entity,which is to be knowable.

This is why Krishna says in Bhagavad Gita that the Sankhya philosophy is already contained in Bhakti Yoga and only the less intelligent class of men make a distinction between Sankhya-yoga and Bhakti-yoga.
