AIZAWL, JUNE 18: Late at night, a mixed group of nude high school students huddle together in a circle inside a cemetery, holding hands and chanting invocations to Satan.In the centre of the circle is the skull of a monkey with the inscription `God is Satan' written in reverse. The `worshippers' fall into a trance and one after another slash their wrists in a ritual offering of blood to the Fallen Angel.The increasing popularity of devil worship has caused concern among confused parents and teachers, unable to find out whether the teenagers are taking drug or worse, Aizawl SP Zorammawaia said.This indulgence in witchcraft has confounded the powerful Presbyterian Church here. A four-member Aizawl Theological College faculty authorised by the Presbyterian Church Synod enquired into this craze for Satan worship and submitted a seven page report recently. A copy of the report was also submitted by Church Elder Lalliansawta to Zorammawia.Zorammawia said the Church Elder had requested the police to look into devil worship as it was "a social menace and could lead to many social evils."
