FIVE YEARS AGO, three books turned Ip Pui's life upside down, hurtling her into a stark new world.
The paperbacks compelled the Hong Kong woman to uproot from her comfortable two-bedroom flat in Sai Kung and job as a journalist at the Oriental Weekly newspaper and relocate to Calcutta, a place she now calls home.
Today, Ip slogs six days a week in Calcutta's Nirmal Hriday (Pure Heart) refuge for the dying and destitute run by the Missionaries of Charity (MOC) order founded by Catholic nun Mother Teresa.
She tends lovingly to diseased and terminally ill, including beggars and prostitutes, picked up from the streets by MOC nuns so that they can at least die with dignity at the centre, close to Calcutta's holiest religious shrine - the Kali Temple.
Since her arrival in early 1999, the thirty-something's duties have included cleaning, administering medicine, dressing wounds, and feeding, bathing and massaging those who've fallen through the cracks of Indian society.
The ever-smiling and energetic Hong Kong woman is conspicuous among fellow volunteers from the US, Europe, South Africa, Japan and South Korea. She is the lone Chinese among the scores of overseas volunteers who flock from all parts of the world to help the nuns in 19 Calcutta facilities, which include orphanages for handicapped children and shelters for lepers, Aids patients and the mentally disabled and disturbed.
