James 1:26-27. What is the pure religion?

“If anyone thinks he is religious without controlling his tongue, his religion is useless and he deceives himself.

Pure and undefiled religion before God the Father is this: to look after orphans and widows in their distress and to keep oneself unstained from the world.”
‭‭James‬ ‭1:26-27‬ ‭CSB‬‬
