‘Love is the breath of the Holy Spirit inspired into the human spirit!’
This piece seems to be another version of the better known one that is HERE http://reference.bahai.org/en/t/ab/SAB/sab-13.html
Progress is of two kinds, material and spiritual.
The former is attained through observation of the surrounding existence and constitutes the foundation of civilization.
Spiritual progress is through the breaths of the Holy Spirit and is the awakening of the conscious soul of man to perceive the reality of divinity.
Material progress insures the happiness of the human world.
Spiritual progress insures the happiness and eternal continuance of the soul.
