Srimad Bhagavatam Canto 11, Chapter 17, Text 58

SB 11.17.58

evam grhasayaksipta-
 hrdayo mudha-dhir ayam
atrptas tan anudhyayan
 mrto ’ndham visate tamah
 
Translation: 
 
Thus, because of his foolish mentality, a householder whose heart is overwhelmed by family attachment is never satisfied. Constantly meditating on his relatives, he dies and enters into the darkness of ignorance.
 
Purport: 
 
Andham visate tamah indicates that in his next life an attached householder will certainly be degraded because of his primitive mentality of bodily attachment, which is called mudha-dhi. In other words, after enjoying the sense gratification of considering oneself the center of everything, one enters into a lower species of life. Somehow or other, we must fix our minds on Lord Krsna and come out of the darkness of ignorance to our real life in Krsna consciousness.
 
Thus end the purports of the humble servants of His Divine Grace A.C. Bhaktivedanta Swami Prabhupada to the Eleventh Canto, Seventeenth Chapter, of the Srimad-Bhagavatam, entitled “Lord Krsna’s Description of the Varnasrama System.”
