The Kitáb-i-Aqdas - The Most Holy Book
Index term: influence on spirit of man, under Cleanliness
k76.
God hath enjoined upon you to observe the utmost cleanliness, to the extent of washing what is soiled with dust, let alone with hardened dirt and similar defilement. Fear Him, and be of those who are pure. Should the garb of anyone be visibly sullied, his prayers shall not ascend to God, and the celestial Concourse will turn away from him. Make use of rose-water, and of pure perfume; this, indeed, is that which God hath loved from the beginning that hath no beginning, in order that there may be diffused from you what your Lord, the Incomparable, the All-Wise, desireth.

Cleave ye unto the cord of refinement
'Abdu'l-Bahá refers to the effect of "purity and holiness, cleanliness and refinement" on the exaltation of "the human condition" and "the development of man's inner reality". He states: "The fact of having a pure and spotless body exercises an influence upon the spirit of man." (See also note 74.)
