Here's a snippet from Watchman Nee, read the whole quote from Dev:
Now the breaking of the alabaster box and the anointing of the Lord filled the house with the odor, with the sweetest odor. Everyone could smell it. Whenever you meet someone who has really suffered; been limited, gone through things for the Lord, willing to be imprisoned by the Lord, just being satisfied with Him and nothing else, immediately you scent the fragrance.
There is a savor of the Lord. Something has been crushed, something has been broken, and there is a resulting odor of sweetness. The odor which filled the house that day still fills the Church; Mary's fragrance never passes away.
...We like to be always "on the go": the Lord would sometimes prefer to have us in prison. We think in terms of apostolic journeys: God dares to put His greatest ambassadors in chains. "But thanks be unto God, which always leadeth us in triumph in Christ, and maketh manifest through us the savor of his knowledge in every place" (2 Corinthians 2:14)
