NERVOUS believers fear it to be spooky, disbelievers dismiss it as plain hallucination, while adherents attest to its power. But mediums claim they hold the key to a walkway to the spirits, often those of their beloved dead. And Mumbai, despite its overt materialism, also quarters the otherworldly. In fact, many, including Rhea Pillai, dancer Shiamak Davar, industrialist Yash Birla, have accessed it. Davar has regular heart-to-hearts with his dead gran, Birla has found solace after the soul-crushing death of his parents and sister in an air-crash, while Pillai communed with a spirit to confirm if her beau, filmstar Sunjay Dutt, would find reprieve from his incarceration.
