153. God hath removed the restrictions on travel that had been imposed in the Bayán. [#131]
The Báb decreed certain restrictions on travel which were to remain in force until the advent of the Promised One of the Bayán, at which time the believers were instructed to set out, even if on foot, to meet Him, since the attainment of His presence was the fruit and purpose of their very existence.
154. Raise up and exalt the two Houses in the Twin Hallowed Spots, and the other sites wherein the throne of your Lord ... hath been established. [#133]
Bahá’u’lláh identifies the "two Houses" as His House in Bag̱ẖdád, designated by Him as the "Most Great House", and the House of the Báb in S̱ẖíráz, both of which have been ordained by Him as sites of pilgrimage. (See Q and A 29, 32 and note 54.)
Shoghi Effendi explained that "the other sites wherein the throne of your Lord ... hath been established" refers to those places where the Person of the Manifestation of God has resided. Bahá’u’lláh states that "the people of the areas where these are situated may choose to preserve either each house" wherein He resided, "or one of them" (Q and A 32). Bahá’í institutions have identified, documented, and where possible, acquired and restored a number of the historical sites associated with the Twin Manifestations.
155. Take heed lest ye be prevented by aught that hath been recorded in the Book from hearkening unto this, the Living Book [#134]
The "Book" is the record of the revealed Word of the Manifestations of God. The "Living Book" is a reference to the Person of the Manifestation.
These words contain an allusion to a statement of the Báb in the Persian Bayán about the "Living Book", which He identifies as Him Whom God will make manifest. In one of His Tablets Bahá’u’lláh Himself states: "The Book of God hath been sent down in the form of this Youth."
