Emotions

The natural emotions are blameworthy and are like rust which deprives the heart of the bounties of God.

‘Abdu’l-Bahá, The Promulgation of Universal Peace, p. 244-245

These are the divine appearances, the heavenly bounties, the sublime emotions, the love and knowledge of God; universal wisdom, intellectual perception, scientific discoveries, justice, equity, truthfulness, benevolence, natural courage and innate fortitude; the respect for rights and the keeping of agreements and covenants; rectitude in all circumstances; serving the truth under all conditions; the sacrifice of one's life for the good of all people; kindness and esteem for all nations; obedience to the teachings of God; service in the Divine Kingdom; the guidance of the people, and the education  of the nations and races. This is the prosperity of the human world! This is the exaltation of man in the world! This is eternal life and heavenly honor!

‘Abdu’l-Bahá, Some Answered Questions, p. 79-80

When man's soul is rarefied and cleansed, spiritual links are established, and from these bonds sensations felt by the heart are produced. The human heart resembleth a mirror. When this is purified human hearts are attuned and reflect one another, and thus spiritual emotions are generated.

‘Abdu’l-Bahá, Selections from the Writings of ‘Abdu’l-Bahá, p. 108

The emotions that have possessed my grieving heart are such that they cannot be put into words, and tongue and pen are helpless to describe them."
