Meditation and Significance of Scientific Research


Around 1,500 BCE in the ancient scriptures, the Vedas (in Aranyaka and Brahmana layers of the Vedas) we see the mention of meditation .In Upanishads it is expressed as contemplation; as a path towards realization of self. Sage Patanjali's laid the path towards self-realization through Ashtanga yoga where dhyana is the seventh limb that leads to Samadhi sthiti.

Dhyana derived from the Sanskrit root Dhi meaning "imaginative vision" and dhyana, or "meditation, contemplating, reflecting on whatever Dharana has focused on. Meditation or dhyana is a process of raising spiritual energy towards enlightenment. Under the regular guidance of a "guru" the "dispeller of darkness” one can begin the inward journey, journey to the self.

Dhyana- seventh limb of Ashtanga yoga:-

Sage Patanjali’s emphasizes on the practice of all the eight libs of Ashtanga yoga in the order to reap the fruit of self-realization. Practicing Yama, niyama asana and pranayama are vital for a practitioner to prepare his physical body for anatarmukha sadhana, towards dhyana. .regular practice of pranayama helps to regulate the breath, calm the mind, relaxes the body.

Thus regular practice of asana and pranayama align the energy centers of the body suitable for the free flow of prana Shakti within the body and aids the practice of dhyana.

Asan for meditation:-

Meditation postures vary with the technique chosen. Regarding seated meditation techniques few do not emphasis to be at ease while most emphasize sitting relaxed, erect, with spine straight, folded legs, hands resting on the laps above the knee forming gyan or any meditative mudra and with relaxed neck .basically, we should be able to practice meditation comfortably with no bodily discomfort for experiencing its true essence. Hence the emphasis on practicing Asan and pranayama. E.g. Padmasan, sukhasan, swastiksasn. practicing in the early hours of the day, in the brahma muharta is ideal, before going to bed begin with can practice for a minimum of ten minutes and slowly your body will guide along the process and can try for half an hour which varies for each individual. Diet plays an important role in this process, sadhana. Diet that is suitable for our body and satvic is we practice meditation as per Ashtanga yoga, our body as well our mind guides us as to what it wants to have. We need to listen to our body and become aware and acknowledge its suggestions.

I quote, “if you can master the nine gates of your body-eyes, ears, mouth, nose, sex organ and rectum –then all the secrets of nature will open to you.”-Yogi Bhajan

Purpose of meditation:-

Acharya Shriram Sharma: “Meditation is the key for opening the doors of mysteries to your mind.”

Through meditation we can observe our mind, become conscious of the various functions of the mind namely manas, budhhi, ahamkar and chitta. Meditation is a time with our “self”. A time to connect with our breath, to be in the present, to re-establish the rhythm within. Meditation is a process of cleaning and calming the mind; knowing the power within. Truly a divine experience.

Individuals becoming more aware of health and wellbeing meditation is a like prevention is better than cure. Anxiety and stress related problems have impact on once health.

 Udupa, (2000) explains, “Anxiety is an excessive out pouring of acetylcholine from the cerebral cortex which stimulates the autonomic nervous system, mainly the sympathetic nervous system .this in turn produces excess of adrenalin and nor-adrenalin. These neuro-hormone circulate in blood to produce a series of changes in the functioning of various organs, resulting in tachycardia, hypertension, tremors, excessive perspiration etc. because of the interference with circulation in skeletal muscles there occurs anaerobic cellular metabolism leading to excessive liberation of lactates into the blood, leading to rise in the occurrence of psychosomatic diseases.”

Pandya (april,1994) said that “Devotional practice of meditation with purity of thoughts results in the secretion of various neurotransmitters like Dopamine, Acetylcholine GABA, Serotonin, Endorphins and encephalin in regulated manner which in turn increases the internal happiness, concentration, memory, emotional maturity and over all body energy of the practitioners.

When we practice meditation, it causes a significant alteration in brain usage patterns, neural chemistry, and emotional balance, inducing relaxation, regulating attention, and developing an attitude of detachment from one's own thoughts. Evidence from a meta-analysis of ten neuroimaging studies suggest that the caudate body, entorhinal cortex, and medial prefrontal cortex have a central role in supporting the general aspects of meditation effects. Each mediation technique is unique while the basic aim being relaxation. Becoming aware and transforming ones state of mind, turning inwards to concentrate on the inner self is its true essence its purpose.

Research study and significance:-

The role of scientific study in this field of meditation and studying the human master brain is immense. There are several studies of the brain, namely PET and f-MRI that identified several brain areas linked to anxiety or psychological problems (Davidson, et all 1999).several studies by (ter, et all 1998), (Nordahl, Benkelfat, Semple, Gross and King, 2000) consistently implicate that cingulate as well as amygdala, hippocampus, thalamus and hypothalamus in most types of mental disturbances (Swedo, et all 2004). Studies show that  anxiety is associated with several neurotransmitters and hormones, including excitatory amino acid glutamate, inhibitory amino acid - aminobutyric acid, and other neurotransmitters and neurochemical compounds such as catecholamine’s, dopamine, cholecystokinin, corticotrophin-releasing hormone . Also increased blood pressure, increased glucose and cortisol level, immune system and digestion shut down, acidic skin, etc.

Researchers studied various meditation techniques and their effect on the overall wellbeing of the per studies, meditation may release emotional and mental blockages, from abuse and traumatic images to unprocessed anxiety, grief or anger.

Join us to know more meditation techniques, their research study and the benefits of practicing that particular technique .like it is said every individual is unique and prefers a technique suitable to his requirements, maybe you might get insights of a beautiful technique of your own. Would be interesting to know your important views in the comments section. Thank you.

“If meditation has its full impact, the body begins to secrete nectar or ambrosia, which symbolizes immortality.

Meditation has really deep chemical effects on the body.

The body begins to perceive, think and understand things in a different way altogether. All the electric circuits of the body change.”- Osho
