fundamental element that is air. Diseases are most often caused by a disruption of air circulation in the terrestrial body of separate beings. Psychic disorders, more particularly, have their origin in a particular dysregulation of the air in the body, and yogic exercises have a remarkably beneficial action on the balance of these subtle airs and allow to eradicate the disease in almost all . When these yogic exercises are practiced properly, they have the effect of increasing the duration of existence and conferring control over one's own death. Thus, a perfect spiritualist can dominate his death and leave his body at the right time, when he is able to rise to the planet of his choice. However, the devotional service offered to God is superior to any other spiritualist because, by the force of his devotional service, he is promoted to the world which extends beyond the material galaxy, and transported on one of the planets of this spiritual world, by the supreme will of the Lord who directs all things.

It is the interest of the soul that must be sought, not that of the body.

Whoever accumulates goods in this material world such as wealth, land, houses, relationships, friends and children, never possesses them for a time. No one can keep eternally all these illusory treasures, creations of Maya, the energy of illusion of the Lord, which are all factors of error in the path of spiritual realization. It would be better to be content with less, or even own nothing at all, and thus remain free from inappropriate pride.

As a result, the more one progresses spiritually on the path of devotional service offered to the Lord, the more one frees oneself from the attachment to material illusion. A firm conviction as to the spiritual life and its permanent effects is however necessary to achieve this goal.

To be able to truly realize the permanent nature of spiritual existence, one must voluntarily learn to suffice the minimum so that one can easily provide for all his needs. By avoiding the creation of artificial needs, man will more easily manage to be satisfied with the minimum. By “artificial needs” we mean activities aimed at the pleasure of the senses, on which, moreover, the current evolution of civilization is based. Now, a perfect civilization finds its foundation not in the pleasure of the senses, but in the soul. So-called civilized men, but who live only for the pleasure of the senses, are hardly better than animals; indeed, the latter cannot rise beyond the activity of the senses. Although the mind is superior to the senses, a civilization based on speculative thinking is by no means a perfect society. Beyond the mind is
