Convey on behalf of ‘Abdu’l-Bahá to thy respected wife my Abhá greetings, and say: “Kindness, training and education extended to prisoners is exceedingly important. Therefore as thou hast exerted an effort in this, hast awakened some of them, and hast been the cause of the turning of their faces to the divine Kingdom, this praiseworthy deed is highly acceptable. Assuredly persevere. Convey on my behalf to the two prisoners in San Quentin the utmost kindness, and tell them: ‘That prison in the sight of wise souls is a school of training and development. Ye must strive with heart and soul that ye may become renowned in character and knowledge.’”
