You have observed that while ‘Abdu’l-Bahá was in the utmost bodily weakness and feebleness, while he was indisposed, and had not the power to move—notwithstanding this physical state he traveled through many countries, in Europe and America, and in churches, meetings and conventions was occupied with the promotion of the divine principles and summoned the people to the manifestation of the Kingdom of Abhá. You have also observed how the confirmations of the Blessed Perfection encompassed all. What result is forthcoming from material rest, tranquillity, luxury and attachment to this corporeal world? It is evident that the man who pursues these things will in the end become afflicted with regret and loss.
