From a February 2001 interview with Arianna Huffington in the Boston Globe:

โ€œI advocate tithing, giving 10 percent of oneโ€™s income, for those who can afford it, to poverty-fighting specificallyโ€ฆI give 10 percent of my gross income to poverty-fighting.โ€

From the LA TImes today:

Huffingtonโ€™s tax form lists $46,763 in contributions to charity in 2002. Those were not deductible because she had no taxable income.

The contributions include payments to three prominent private schools on Los Angelesโ€™ Westside โ€” the Archer School, Crossroads and New Roads. They also include payments of $6,675 to the Church of the Movement of Spiritual Inner Awareness and a related foundation.

The church, founded by John-Roger, describes itself as designed to โ€œteach Soul Transcendence, which is becoming aware of yourself as a Soul and as one with God, not as a theory but as a living reality.โ€โ€
