Feelings of security derived from material things is illusion

From srila Prabhupada's purport to SB 4.25.55

When the living entity is encircled by wife, children and home, he acts on the mental plane. Sometimes he is very happy, sometimes he is very much satisfied, sometimes he is not satisfied, and sometimes he is bewildered. Bewilderment is called moha, illusion. Illusioned by society, friendship and love, the living entity thinks that his so-called society, friendship and love, nationality, community, etc., will give him protection. He does not know that after death he will be thrown into the hands of a very strong material nature that will force him to accept a certain type of body according to his present work. This body may not even be a human body. Thus the living entity’s feeling of security in this life in the midst of society, wife and friendship is nothing but illusion. All living entities encaged in various material bodies are illusioned by the present activities of material enjoyment. They forget their real business, which is to go back home, back to Godhead.

Everyone who is not in Kṛṣṇa consciousness must be considered to be in illusion. One’s so-called feelings of happiness and satisfaction resulting from material things are also illusions. Factually neither society, friendship, love nor anything else can save one from the onslaught of the external energy, which is symptomized by birth, death, old age and disease. To get even one living entity out of the illusory condition is very difficult; therefore Lord Kṛṣṇa says in Bhagavad-gītā (7.14):

daivī hy eṣā guṇa-mayī
 mama māyā duratyayā
mām eva ye prapadyante
 māyām etāṁ taranti te

“This divine energy of Mine, consisting of the three modes of material nature, is difficult to overcome. But those who have surrendered unto Me can easily cross beyond it.” Therefore, unless one surrenders completely at the lotus feet of Kṛṣṇa, he cannot get out of the entanglement of the three modes of material nature.
