Revisiting Burari Horror

The infamous Burari incident is back in limelight after docu-series House of Secrets: The Burari Deaths on Netflix, opened up the infamous mass suicide case.
On the morning of 1st July, 2018, 11 members of Chundawat family were found dead at their home in Delhi's Burari. Ten of them were found hanging from the ceiling. The eldest woman, 80-years-old Narayni Devi, was found strangled in another room.
Murder or Suicide?
It was initially considered a murder case. However, there were no signs of forced entry. In the courtyard, 10 of the family, including two teens, were found hanging with their mouths taped and blindfolded. Some of the bodies had their hands and feet tied as well.
Occult Practice?
During probe, the police recovered 11 diaries, maintained over 11 years, from the house. One of the diaries had a detailed note on a ritual that required the family members to tie their hands and feet, similar to how the 10 bodies had their limbs tied.
While there was no conclusive reason as to why a normal-looking middle class family would take their own lives, it turned out that Lalit, the patriarch of the house, apparently suffered from a delusional disorder. The family trusted Lalit and followed his orders religiously.
As police were investigating to know if it was a murder or suicide, 11 pipes emanating from the wall of the Burari house intrigued everyone. No one could understand the purpose of those 11 pipes emerging from the house where 11 of a family were found dead.
The family blindly trusted Lalit, 45, Narayni Devi's second son. He had drastically changed after his father's death in 2006 and few accidents. In fact, the notes in the diaries were found to be in a conversational tone wherein Lalit was apparently talking to the spirit of his deceased father, who would guide him on matters of daily life.
