Vishnu - the Preserver
To understand the concept of Vishnu being the preserver of the world, one has to understand the two beliefs of Hinduism. The first is that men attain salvation by faithfully following predetermined paths of duty. The Second is that powers of good and evil (gods and demons) are in regular controversy to rule over the world. It is believed that whenever evil prevails over good in order to win, Vishnu comes down to earth in some mortal form to save righteousness. As per the Puranas, Vishnu is not allowed to interfere in the situations directly. So, he takes different avatar and act in manners that will re-establish proper balance between good and evil.

The weapons of Vishnu, such as the discus, mace, and conch shell, symbolize his power and ability to protect and preserve the universe in Hindu mythology. These weapons are used by Vishnu to maintain order and defeat evil forces, showcasing his role as a preserver and protector in the Hindu pantheon.
Hindu consider him as the preserver of the universe, a loving and forgiving figure who brings salvation.
The three main gods are Brahma (the creator), Siva or Shiva (the destroyer) and Vishnu (the preserver).
All Gods or Goddesses preserve the universe, whether it is Shiva, Vishnu, or the Mother Goddess, Durga. But most hindus worship Vishnu (they are known as Vaishnavas and make the majority of hindus) and consider him to be the preserver God.
Kalyug will end when the 10th and last incarnation of Vishnu is born on the mortal earth. This incarnation of the Hindu Preserver will be called Kalki.
The chief deity of the Hindu pantheon is Brahma, the Creator. He is, of course, part of a holy trinity, along with Vishnu the Preserver and Shiva the Destroyer.
Lord Narayana is the preserver.The actual Hindu preserver god:Vishnu - the preserver:Every Hindu knows Vishnu, also known as Narayana, as the preserver.This is because he is symbolic of the Semi voluntary force. This force makes everything in our life to stay between an upper and a lower limit, due to the presence of the Negative and the Positive attitudes. Vishnu would not allow as to cross these limits under normal conditions.Vishnu - the transformer:Due to incarnations, Vishnu enables us to change enormously between these two limits.1. Rama, symbolic of the negative attitude, enables us to be totally satisfied with whatever we have and be adherent to dharma even under extreme conditions.2. In marked contrast, Krishna, symbolic of the Positive attitude, enables us to succeed at all costs.3. Venkateshwara, another incarnation of Vishnu, enables us to have just a virtual existence between the attitudes and acquire wealth compulsively yet safely. He is undoubtedly, the most acceptable Hindu god in this materialistic world.Thus, even though Vishnu is known as the preserver, he allows us to change our life more than any other Hindu god.The actual Hindu preserver god:The Hindu god, which eternally doesn't allow even the minutest change in our life under any condition, is Brahman. Thus, Brahman is the absolute and eternal Hindu preserver, of dharma and of our life.The popular preserver:Since most Hindus can't understand Brahman and don't want the rigidity Brahman gives, they consider Vishnu himself as the preserver.
