Spiritual effects of travel teaching/pioneering

In speaking of spreading the fragrances of the Kingdom, ‘Abdu’l-Baha said:

"In movement there is life; in immobility there is death. The traveling of the teachers from place to place, country to country, and from the Occident to the Orient, is one of the greatest means for sowing spiritual seeds in the souls of the people." 

- 'Abdu'l-Baha  (Words of ‘Abdu’l-Baha, recorded by Howard Stuven and Charles Mason, Haifa, May 1910; Star of the west, vol. 1, no. 11, September 27, 1910)

When teaching the Cause one should speak from the heart

…’Abdu’l-Baha said that the teacher should always speak from the heart, for only words from the heart reach the hearts of the hearers and has effect, whereas when one speaks not from the heart, the effect of his words is but a passing one. All teaching should be done by the Spirit working or speaking through the teacher, and should not come from the mentality of the individual. One should always use spiritual methods in teaching.

Inspiration

The heart, when pure and free, becomes inspired.
