Knicks president Phil Jackson is trying to sell Lakers free-agent power forward Pau Gasol on the proximity of the United Nations, playing with Carmelo Anthony and extending his career in the triangle offense.

As Jackson awaits official word from Anthony, he’s trying to coax the 7-foot Spaniard to forget about the money and be part of the rich fabric of New York.

A source told The Post new Knicks point guard Jose Calderon also has texted his countryman/friend Gasol several times about joining him in New York.

“Pau knows Jose wants him on the team,’’ the source said.

The Post reported one reason Anthony is close to re-signing is having a shot at the 34-year-old Gasol, who then could recruit his brother, Marc Gasol. The Memphis center is a free agent in 2015 when the Knicks should have plenty of cap space.

Pau, however, would have to take less to play in New York for Jackson, his former coach, and for rookie coach Derek Fisher, Gasol’s former teammate.

“[Gasol] knows what he has here and what is possible,’’ Jackson said during the Knicks summer league practice. “He’d like to play with Carmelo and like to play with a winner. We can’t guarantee that, but with him we can guarantee a much better chance.’’

Jackson indicated he called Gasol on his birthday Sunday to offer best wishes, then sell the Knicks.
