Moderation

In all circumstances they should conduct themselves with moderation.

Bahá’u’lláh, Lights of Guidance, p. 294

Overstep not the bounds of moderation.

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 235

The civilization, so often vaunted by the learned exponents of arts and sciences, will, if allowed to overleap the bounds of moderation, bring great evil upon men. Thus warneth you He Who is the All-Knowing. If carried to excess, civilization will prove as prolific a source of evil as it had been of goodness when kept within the restraints of moderation.

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 342

The word of God which the Supreme Pen hath recorded on the ninth leaf of the Most Exalted Paradise is this: In all matters moderation is desirable.

Bahá’u’lláh, Tablets of Bahá’u’lláh, p. 68

Thou hast written that they have pledged themselves to observe maximum austerity in their lives with a view to forwarding the remainder of their income to His exalted presence. This matter was mentioned at His holy court. He said: Let them act with moderation and not impose hardship upon themselves. We would like them both to enjoy a life that is well-pleasing.

Bahá’u’lláh, Huqúqu’lláh, p. 20

Whatsoever passeth beyond the limits of moderation will cease to exert a beneficial influence.
