HOw does the religious art of Hinduism represent the divine?

Question

how does that reflect its understanding of ultimtimate reality

Answer 1

Since Hinduism believes in reincarnation, it follows that our actions in this life can determine what kind of tendencies we will be born with in subsequent lives. Virtuous actions take the soul closer to the Supreme Divine and lead to a birth with higher consciousness. Evil actions hinder this recognition of the Supreme Divine, and the soul takes lower forms of worldly life.

Therefore, Hinduism teaches, we should try to behave in a virtuous manner as much as possible, so that we will develop good habits and tendencies both in this and the next life. Over the course of time, if one can sufficiently purify his or her mind, one can attain the goal of life: experience of the highest truth, which is God.

Answer 2

In the Srimad-Bhagavatam (1.2.11) the conception of the Absolute Truth is explained thus:
The Absolute Truth is realized in three phases of understanding, namely

“The Absolute Truth is realized in three phases of understanding by the knower of the Absolute Truth, and all of them are identical. Such phases of the Absolute Truth are expressed as
Brahman, or the impersonal all-pervasive spirit;
Paramatma, or the localized aspect of the Supreme within the heart of all living entities; and
Bhagavan, or the Supreme Personality of Godhead, Lord Krishna”

These three divine aspects can be explained by the example of the sun, which also has three different aspects, namely the sunshine, the sun’s surface and the sun planet itself.
One who studies the sunshine only is the preliminary student. One who understands the sun’s surface is further advanced. And one who can enter into the sun planet is the highest. Ordinary students who are satisfied by simply understanding the sunshine—its universal pervasiveness and the glaring effulgence of its impersonal nature—may be compared to those who can realize only the Impersonal feature of the Absolute Truth. The student who has advanced still further can know the sun disc, which is compared to knowledge of the Paramatma (God being situated in the Heart) feature of the Absolute
Truth. And the student who can enter into the heart of the sun planet is compared to those who realize the personal features of the Supreme Absolute Truth.
Therefore, the transcendentalists who have realized the Bhagavan (Personal) feature of the Absolute Truth, are the topmost transcendentalists.
Although all students who are engaged in the study of the Absolute Truth, are engaged in the same subject matter.
The sunshine, the sun disc and the inner affairs of the sun planet cannot be separated from one another, and yet the students of the three different phases are not in the same category.

Answer 3

There are many different types of Hindus, some are poly-theistic and would represent the divine in multiple ways, others are monotheiestic .... the primary belief is reincarnation, where all of us are reborn, again and again, in relation to how we lived our prior life.
