Part 3b.2 - Holding the object one-pointedly

Then coarse discursive thoughts are suppressed, and after meditating in that way: Practice the four immeasurables and the two bodhicittas.
Then, within the practice of the developing stage, Meditate in one-pointed attention without distraction On whatever spiritual object may be appropriate, Such as a picture or a book of the holy texts.

Then train in the four immeasurables, kindness and so forth or in the bodhicittas of aspiring and entering. The Bodhicharyavatara says:

Thoughts should be completely pacified
And we should meditate on bodhicitta.

Do that or practice the developing stage. The Dohakosha says:

Grasp with the mind the form of the deity, painted etc.

The Samadhiraja Sutra says:

With a statue that is gold in color,
Entirely beautiful, of the Lord of the World,
The mind of one into whom this image enters
Meditates in the way of a bodhisattva.

In brief, those previously unfamiliar with the former objectless meditation can take some appropriate good object and meditate on it without being distracted to anything else. The Mahayanasutralankara says:

Having focused the mind on the object of meditation,
Never let yourself be distracted away from it.
