Friends:

Formless are the Fruits of the 4 Infinite States:

The Blessed Buddha once pointed out some fine future fruits:
The release of mind by universal friendliness developed, when linked with
the 7 links to Enlightenment, has the beautiful liberation as culmination!

The release of mind by compassionate pity developed, when all joined with
the 7 links to Enlightenment, has the infinitude of space, as culmination!
This is the 1st formless absorption.

The release of mind by altruistic and mutual joy developed, when all linked
with the 7 links to Enlightenment, has the infinitude of consciousness,
as its ultimate culmination... This is the 2nd formless absorption..

The release of mind by imperturbable equanimity developed and combined
with the 7 links to Enlightenment, has the void sphere of nothingness, as its
absolute culmination... This is the 3rd formless absorption.

So do these 4 divine and infinite states of friendliness, pity, mutual joy and
equanimity, when cultivated fused together with the 7 links to Enlightenment:
Awareness, Investigation, Energy, Joy, Tranquillity, Concentration and finally
Equanimity, lead to entry, and absorption into these 4 sublime and formless
mental dimensions of exquisitely subtle supra-mundane consciousness...

From Delight in Diversity to Unification in Oneness...
