The 17-year-old, who took his own life, was laid to rest following a ceremony at Newlands Cross crematorium earlier today.
Taking to Twitter this afternoon, Sinead said “Shaney” would have loved it.
“He was always chanting ‘Om. Shanti’,” she wrote. “I put a few packs of fags in the coffin for him in case there’s none in heaven. He’ll have loved that too. Om. Shanti.”
The phrase that appears in Buddhist prayers, writings and ceremonies is an invocation for peace.
She also tweeted a link to another mantra that she had been playing for “Shaney” all week.
“Only this morning did I notice the date it was uploaded to YouTube. March 10. That was Shane’s birthday,” she added.
She also requested that if people were going to send anything to the mortuary at Loughlinstown Hospital or Newlands Cross crematorium, to “please send flowers or Hindu objects.”
Meanwhile, a memorial service for Shane is to take place in Bray, Co Wicklow tomorrow evening after close family and friends paid their respects at the funeral home where Shane reposed last night.
Folk musician Donal Lunny and Sinead told how they will "lovingly remember forever" tragic son Shane in an online death notice.
The teenager had gone missing last Thursday week, before gardai confirmed he had been "located deceased" last Saturday.
Sinead described Shane as the "very light of my life" on Twitter.
The memorial service for family and friends to celebrate Shane’s life will take place in The Martello, Bray from 2pm to 5pm.
A post on RIP.ie stated that Covid vaccination certificates and face coverings will be required at the ceremony.
It is now expected that a series of inquiries will get underway.
Gardaí are assisting the coroner in preparing a file for the inquest, while the National Review Panel (NRP) - which examines serious incidents including the deaths of children known to child protection services - will also investigate his death.
Meanwhile, an independent review panel will investigate the circumstances surrounding Shane’s death.
