The kṛpaṇas, or miserly persons, waste their time in being overly affectionate for family, society, country, etc., in the material conception of life. One is often attached to family life, namely to wife, children and other members, on the basis of "skin disease." The kṛpaṇa thinks that he is able to protect his family members from death; or the kṛpaṇa thinks that his family or society can save him from the verge of death. Such family attachment can be found even in the lower animals, who take care of children also. Being intelligent, Arjuna could understand that his affection for family members and his wish to protect them from death were the causes of his perplexities. Although he could understand that his duty to fight was awaiting him, still, on account of miserly weakness, he could not discharge the duties. He is therefore asking Lord Kṛṣṇa, the supreme spiritual master, to make a definite solution.
(Bhagavad-Gita--2:7--purport).

For example, sex enjoyment is a necessity for the conditioned soul, and sex enjoyment is allowed under the license of marriage ties. According to scriptural injunctions, one is forbidden to engage in sex relationships with any women other than one's wife. All other women are to be considered as one's mother. But in spite of such injunctions, a man is still inclined to have sex relationships with other women. These propensities are to be curbed; otherwise they will be stumbling blocks on the path of self-realization. As long as the material body is there, the necessities of the material body are allowed, but under rules and regulations.
(Bhagavad-Gita-3:34-purport).

The description in the Vedas indicates that the Lord glanced over the prakṛti, or nature, and impregnated it with atomic individual souls. All these individuals are working in the material world for sense gratification, and under the spell of material energy they are thinking of being enjoyers. This mentality is dragged to the last point of liberation when the living entity wants to become one with the Lord. This is the last snare of māyā, or sense gratificatory illusion, and it is only after many, many births of such sense gratificatory activities that a great soul surrenders unto Vāsudeva, Lord Kṛṣṇa, thereby fulfilling the search after the ultimate truth.
(Bhagavad-Gita--2:39--purport).
