The Bhagavad Gita, a sacred text in Hinduism, explains the concept of Gunas in detail. In chapter 14, verse 5, Lord Krishna explains:

सत्त्वं रजस्तम इति गुणाः प्रकृति-सम्भवाः।

निबध्नन्ति महाबाहो देहे देहिनमव्ययम्॥

"सत्त्वरज और तम - ये तीन गुण प्रकृति से उत्पन्न होते हैं और इन गुणों से हमारी अविनाशी आत्मा को शरीर से बाँधा जाता है। हे महाबाहो! ये गुण हर देही में निहित होते हैं और उनके द्वारा हमारे कर्म व्यवहारों को बाँध दिया जाता है।".


"Sattvam rajas tama iti gunah prakriti-sambhavah

Nibadhnanti mahabaho dehe dehinam avyayam"

The Bhagavad Gita also explains that while the Gunas (Sattva, Rajas, and Tamas) are present in every person, they are not fixed or permanent. Through spiritual practice and self-discipline, a person can elevate their consciousness and gradually reduce the dominance of Rajas and Tamas, and increase the influence of Sattva. This process of self-transformation is known as "Sattva-guna-variety" or the attainment of Sattva Guna.

O Bhagavad Gita também explica que, embora os Gunas (Sattva, Rajas e Tamas) estejam presentes em todas as pessoas, eles não são fixos ou permanentes. Por meio da prática espiritual e da autodisciplina, uma pessoa pode elevar sua consciência e gradualmente reduzir o domínio de Rajas e Tamas e aumentar a influência de Sattva. Este processo de autotransformação é conhecido como "variedade Sattva-guna" ou a obtenção de Sattva Guna.

Sattva, Rajas, and Tamas are three Guna qualities mentioned in ancient Indian philosophy, specifically the Samkhya school of thought. These Gunas are thought to represent the universe's building blocks, influencing the properties of everything in it, including humans.


Sattva is a characteristic associated with purity, harmony, and balance. It is linked to attributes like tranquilly, compassion, knowledge, and wisdom. When Sattva rules, a person feels inner calm and contentment, and their activities are led by a sense of purpose and understanding.

There is also a study on the effects of meditation, which is frequently associated with Sattva. Meditation has been shown in studies to improve mental and physical health by reducing stress and anxiety, enhancing attention and cognitive performance, and even increasing immune function.


Rajas is the quality of being active, passionate, and restless. It is linked to aspirations, ambitions, and emotions like rage, envy, and greed. When Rajas is dominant, a person has an insatiable desire for stimulation and is motivated by the pursuit of pleasure, power, and success. 


Tamas is a trait associated with lethargy, dullness, and ignorance. It has been linked to laziness, procrastination, and hallucination. When Tamas is dominating, a person feels confused, drowsy, and lacks ambition or excitement.

Similarly, there has been research on the consequences of stress, which can be linked to Tamas. Chronic stress has been shown to have a harmful impact on both mental and physical health, increasing the risk of depression, anxiety, and cardiovascular disease.

 Scientific words on this aspect along with psychological evidence

      Sattva, Rajas, and Tamas are ancient Indian philosophical notions that have traditionally been associated with spirituality and the road to self-realization. While no direct scientific research has been conducted on these specific concepts, some studies have investigated related aspects of human psychology and behaviour that may be relevant.

        For example, psychological study has looked into personality traits that can be linked to the Gunas. Openness, conscientiousness, extraversion, agreeableness, and neuroticism are the Big Five personality qualities. These characteristics have been linked to many elements of mental and physical health, as well as social and economic outcomes.

There is some evidence that meditation, which is commonly associated with the Sattva guna, can have a favourable effect on the neurological system.

Regular meditation has been shown in studies to cause changes in brain activity, such as increased activity in the prefrontal cortex, which is connected with attention, decision-making, and self-control. Meditation has also been shown to boost activity in the insula, which is involved in body and emotion awareness.

Furthermore, studies have shown that meditation can have a positive effect on the stress response system. It has been discovered to reduce the activity of the sympathetic nervous system, which is in charge of the fight-or-flight response, and enhance the activity of the parasympathetic nervous system, which is in charge of the rest-and-digest response.

Other research has found that meditation can alter the structure of the brain. It has been discovered, for example, to increase the thickness of the prefrontal cortex and the hippocampus, which are important in learning and memory.

             Overall, while there is still much to learn about the relationship between the Sattva guna and the neurological system, there is evidence that practises associated with Sattva, such as meditation, can have a positive impact on brain activity, the stress response system, and brain structure.
