These horrific pictures show terrified toddlers being thrown from a roof before plummeting 15metres onto a bedsheet below.
The youngsters, who appear to be aged around two, can be heard screaming as they are dangled in the air before being dropped.
This particular ritual took place in the village of Harangal, Parbhani, in western India's Maharashtra.
Hundreds of people turned out for the annual event, which is thought to have been followed by Hindus and Muslims for nearly 700 years in the belief the fall ensures good health and prosperity for their families.
After the child lands and bounces on the bed sheet, held taught by a group of around 14 men, he or she is then quickly passed through the crowd to their mothers.
Another ritual was taking place on the same day in Sholapur, about 280 miles south of Mumbai.

It led to rights activist lashing out at officials who allowed the hundreds of infants to be dropped from the roof of the Baba Umer Durga mosque.
Local officials told television news stations Friday that there had been no reports of injuries.
With high child mortality rates, especially in India's rural areas, many people resort to rituals which they believe can ensure their children's health.
This shows the complete failure of the local administration to prevent this practice and to create awareness about children's health,' said Ranjana Kumari, a civil rights activist in New Delhi.
'It is also a reflection of the lack of access to health services, that forces people to behave in this irrational manner'.
India's National Commission for Protection of Child's Rights issued a notice Thursday to the local administration in Sholapur and has begun investigations into the practice.
