Incarnate beings, haunted by the desire to enjoy material existence, and having therefore accepted as their spiritual master another being as blind as themselves, equally attached to material pleasures and sense objects, cannot understand that the purpose of existence is to return to their original home, located in the kingdom of God, in order to serve Him with love and devotion.

Just as blind people guided by another blind person stray from the ideal path and fall into a ravine, people attached to material life, who allow themselves to be guided by other human beings who are also materialistically minded, are bound by the very strong ropes of self-interested action and endlessly pursue their material existence, subject to the three forms of suffering: those arising from the body and mind, those arising from other living beings, and those arising from material nature (hurricanes, earthquakes, floods, droughts, etc.).

Generally speaking, it can be said that almost all humankind is unaware of the existence of the spiritual world. The knowledge of materialists is extremely limited to the confines of our material galaxy, located in the dark part of creation. They are unaware that beyond our galaxy lies a myriad of others, and even further, the spiritual world.

Unless one perfectly knows God, in His primordial form, and is His devotee, no one can know of the existence of the spiritual world.

Humans, interested only in the material universe, are called blind. These blind people can, of course, be guided by spiritual masters who are just as blind as themselves, for they lack true, genuine knowledge, that which concerns the nature of existence in this world of dense matter. These blind masters, preoccupied with the external, material world, remain forever imprisoned in the powerful bonds of material nature.

Unless one renounces materialism and rejects sense pleasure, it will be very difficult to attach oneself to the Lord and thus be conscious of Him. Only by becoming conscious of Krishna, God, the Supreme Personality, by taking refuge in Him, and by serving Him with love and devotion, can one free oneself from material contamination.
