The decline of distraction and the rise of one-pointedness in the mind is the transformation of samādhi.

Sarvārthatā is distraction, the mind going to all objects. Ekāgratā is one-pointedness, focus on one alone. Kṣaya is decline. Udaya is rising.

This is the second parināma. The mind passes from being scattered among multiple objects to focusing on one alone.

In the ordinary state, attention constantly jumps: thoughts, sensations, memories, anticipations. In samādhi parināma, all this declines and unified concentration arises.

It is not that other objects disappear from the world. They simply cease to attract attention. The mind, by choice and training, remains at a single point.

This parināma describes the quality of meditative concentration. It is the movement from dispersion to unification.

The practice of dhāraṇā gradually produces this parināma. What initially requires effort becomes the natural state of the mind.
