I spent three weeks in Guatemala.
Most of my time was spent in San Marcos Laguna, which is known for being a hippie/spiritual center. Many other travelers referred to it as a "vortex".

The best part was saying "buenos dias" to the locals and seeing their reciprocated smiles.
This may help recreate the calm I felt jumping into Lake Atitlan:
