After the resurrection when Mary encounters Jesus, He tells her not to cling to Him. Why?

Hank Hanegraaff, the host of the 𝘉𝘪𝘣𝘭𝘦 𝘈𝘯𝘴𝘸𝘦𝘳 𝘔𝘢𝘯 broadcast and the 𝘏𝘢𝘯𝘬 𝘜𝘯𝘱𝘭𝘶𝘨𝘨𝘦𝘥 podcast, says that in this case context is important. Jesus is indicating to Mary that their relationship has changed. He now has a transformed glorified body and is about to ascend to heaven.
