The Wheel of Life by Ellen Glasgow

Waking in the night, with a start, Laura asked herself why she had burned the letter. As she lay there in the darkness it seemed to her that the sudden light shone in her thoughts again, and she saw everything made clear to her as she had seen it while she held Jennie Alta's hand. In that instant she had looked beyond the small personal emotions to the woman's soul with its burden of greed and sensuality, and because she had been able to do this, she had felt herself to be composed and released from hatred. To discern the soul was to feel not only tolerance, but pity for the flesh, and it appeared to her now that in that one moment she had ceased to be herself alone, and had shared in the divine wisdom which the sudden light had revealed to her in her breast. Yet the instant afterward her personality had triumphed and she had burned the letter!

The illumination within her faded now, and as she lay there with wide open eyes, she saw only the surrounding darkness. Her own motives were still vague to her; when she tried to remember the prompting of her thoughts she could recall only a physical pain which had entered her bosom while she looked at the large white envelope upon the blotter. "Before this I had never lied in my life," she said, "I had never been capable of the slightest dishonest act, I had even taken a pride in my truth like the pride some women take in beauty -- and yet I did this thing without effort and I do not know now why I did, nor what I thought of at the time, nor whether I regretted it the moment afterward."
