i love reading the speeches of Abdu'l-Baha. His many talks and letters written to people serve as an ocean of guidance and inspiration for how to live as a noble soul, free of prejudice, and sanctified from all of the defilements of this world.
here is an excerpt from one of His messages. i like how He relates the soul to our physical reality, explaining how we can choose to apply our inner spiritual powers to this material world and create a spiritual reality that is free of the darkness of material traits -- traits which relate to our lower nature. reading it stimulates my inner being to develop and embody the myriad of attributes pertaining to living life as a spiritual human being:
'When we speak of the soul we mean the motive power of this physical body which lives under its entire control in accordance with its dictates. If the soul identifies itself with the material world it remains dark, for in the natural world there is corruption, aggression, struggles for existence, greed, darkness, transgression and vice. If the soul remains in this station and moves along these paths it will be the recipient of this darkness; but if it becomes the recipient of the graces of the world of mind, its darkness will be transformed into light, its tyranny into justice, its ignorance into wisdom, its aggression into loving kindness; until it reach the apex. Then there will not remain any struggle for existence. Man will become free from egotism; he will be released from the material world; he will become the personification of justice and virtue, for a sanctified soul illumines humanity and is an honor to mankind, conferring life upon the children of men and suffering all nations to attain to the station of perfect unity. Therefore, we can apply the name "holy soul" to such a one.
'There is, however, a faculty in man which unfolds to his vision the secrets of existence. It gives him a power whereby he may investigate the reality of every object. It leads man on and on to the luminous station of divine sublimity and frees him from all the fetters of self, causing him to ascend to the pure heaven of sanctity. This is the power of the mind, for the soul is not, of itself, capable of unrolling the mysteries of phenomena; but the mind can accomplish this and therefore it is a power superior to the soul.
'There is still another power which is differentiated from that of the soul and mind. This third power is the spirit which is an emanation from the divine bestower; it is the effulgence of the sun of reality, the radiation of the celestial world, the spirit of faith, the spirit His Holiness the Christ refers to when he says, "Those that are born of the flesh are flesh, and those that are born of the spirit are spirit." The spirit is the axis round which the eternal life revolves. It is conducive to everlasting glory and is the cause of the exaltation of humanity.
'In another instance His Holiness the Christ says, "Whosoever has not received a portion of the spirit is as dead. Let the dead bury their dead." This means that although the souls of humanity are living, yet if they are deprived of contact with the spirit they are as dead. In another place Christ says, "You must be baptized with the spirit." This spirit of faith is the flame of reality, the life of humanity and the cause of eternal illumination. It inspires man to attain the virtues and perfections of the divine world.'
