"The VHP will start the 15-day long yatra from tomorrow during which Singhal's mortal remains will be immersed in 50 different rivers across the country," VHP state spokesman Sharad Sharma told PTI.
In Uttar Pradesh, the yatra would begin from Prayag.
"On November 27, the yatra will start from Lucknow and culminate at Ayodhya, where the ashes will be immersed in the Saryu river," Sharma said.
"For Singhal, Ayodhya was his 'karmasthali'...The basic purpose of organising these yatras is to remind the people of his firm resolve to get a temple constructed in Ayodhya," he said.
89-year-old Singhal had died on November 17 following cardio-vascular failure and septicaemia after he was admitted to a hospital in Gurgaon with complaints of acute breathlessness and pneumonia.
The mortal remains of the VHP leader were consigned to flames at Nigambodh Ghat in Delhi the next day.
