Hindus do not believe specifically in one god, many gods or even any gods.
Hinduism is an extremely diverse religion. Although some tenets of the faith are accepted by most Hindus, scholars have found it difficult to identify any doctrines with universal acceptance among all denominations.[12] Prominent themes in Hindu beliefs include Dharma (ethics/duties), Samsāra (The continuing cycle of birth, life, death and rebirth), Karma (action and subsequent reaction), Moksha (liberation from samsara), and the various Yogas (paths or practices).

The Noble Eightfold Path
The eight-spoked Dharmacakra. The eight spokes represent the Noble Eightfold Path of Buddhism.
The Noble Eightfold Path is the way to the cessation of suffering, the fourth part of the Four Noble Truths. This is divided into three sections: Śīla (which concerns wholesome physical actions), Samadhi (which concerns the meditative concentration of the mind) and Prajñā (which concerns spiritual insight into the true nature of all things).
Śīla is morality—abstaining from unwholesome deeds of body and speech. Within the division of sila are three parts of the Noble Eightfold Path:
1. Right Speech—One speaks in a non hurtful, not exaggerated, truthful way (samyag-vāc, sammā-vācā)
2. Right Actions—Wholesome action, avoiding action that would do harm (samyak-karmānta, sammā-kammanta)
3. Right Livelihood—One's way of livelihood does not harm in any way oneself or others; directly or indirectly (samyag-ājīva, sammā-ājīva)
Samadhi is developing mastery over one’s own mind. Within this division are another three parts of the Noble Eightfold Path:
1. Right Effort/Exercise—One makes an effort to improve (samyag-vyāyāma, sammā-vāyāma)
2. Right Mindfulness/Awareness—Mental ability to see things for what they are with clear consciousness (samyak-smṛti, sammā-sati)
3. Right Concentration/Meditation—Being aware of the present reality within oneself, without any craving or aversion. (samyak-samādhi, sammā-samādhi)
Prajñā is the wisdom which purifies the mind. Within this division fall two more parts of the Noble Eightfold Path:
1. Right Understanding—Understanding reality as it is, not just as it appears to be. (samyag-dṛṣṭi, sammā-diṭṭhi)
2. Right Thoughts—Change in the pattern of thinking. (samyak-saṃkalpa, sammā-saṅkappa)
The word samyak means "perfect". There are a number of ways to interpret the Eightfold Path. On one hand, the Eightfold Path is spoken of as being a progressive series of stages through which the practitioner moves, the culmination of one leading to the beginning of another, whereas others see the states of the 'Path' as requiring simultaneous development. It is also common to categorize the Eightfold Path into prajñā (Pāli paññā, wisdom), śīla (Pāli sīla, virtuous behavior) and samādhi (concentration).
now they do however worship the man that wrote this religion but they do not consider him a god.
