To enter the Kingdom is easy, but to remain firm and
constant is difficult. The planting of trees is easy, but their cultivation and
training to strengthen their roots and to make them firm is difficult. Now, as
thou art a firm tree, thou shalt certainly grow and send out branches, leaves
and blossoms and bear fruits.
These branches, leaves, blossoms and fruits are the souls
who may be guided, through the providence of God, by thee. Therefore, thou art
confirmed and strengthened.
- ‘Abdu’l-Baha (‘Tablets of ‘Abdu’l-Baha, vol. 1)
