“Twin Souls,” by Patricia Joudry and Maurie D. Pressman….
“Yang is the initiating impulse, which divides and delineates; yin is the responsive impulse, which nurtures and reunites. Without yang nothing would come into being; without yin all that comes into being would die. yang is mental activity in its forceful aspect, yin the imaginative and poetic, exalting the merely mental to the beautiful. yang goes ahead with things, yin contains things within herself and knows their nature without effort. yang does, yin is. Yang in his givingness bestows the gifts; yin in her being receives, preserves, enhances, and redistributes them. Yang constructs, yin instructs; yang implements, yin complements; yang is strength, yin endurance; yang is knowledge, yin the mystery that reveals itself and becomes knowledge. yang is the discoverer, yin lures toward greater discovery. Yang is the self-developer, inspired by yin, the self dedicator, for her development and his dedication. Yang is the lover, and yin is therefore beloved; yin is the beloved and the source of love. Yang is will and yin is wisdom, and one without the other is neither, and together they are joy. Yang is as the day, turning into night, and yin the night preceding the day; the one is the force that drives the waves of the ocean forward, the other the force that draws them back so that they may go forward again.”
