O thou seeker of the kingdom of God! If thou wishest thy
speech and utterance to take effect in the hardened hearts, be thou severed
from all attachment to this world and turn unto the Kingdom of God. Enkindle
the fire of the love of God in the heart with such intensity that thou mayest
become a flame of fire and a luminous lamp of guidance. At that time thy speech
will take effect within the hearts, through the confirmation of the Holy
Spirit.
- ‘Abdu’l-Baha ('Tablets of ‘Abdu’l-Baha, vol. 1')
