So, I have a proposition to make.
As most of you know that much of Eastern religions (I am thinking of Hinduism, Buddhism etc.) are based on insights that have come from what are called "mystical" experiences of their practitioners. This is also true for the minority mystical traditions in Islam and Christianity which always had a tension with the revelation book based understanding of the scriptures. Now, these mystical experiences had been the outcome of a certain set of meditative practices like yoga, dhyana, mindfulness meditation etc. A typical response of many secular people is to dismiss these experiences as constructs of the mind under these practice regimes and hence devoid of veridicality. However, several decades of research and scientific study has now been made on the impact of these practices on the body and mind of the practitioners and they show, quite unequivocally, that even short period practices of these lead to extremely beneficial effects on the health and mind of the people practicing them...in fact precisely the kind of effects that have been claimed to occur for short term practice of these meditative and yogic practices in the original scriptural traditions on which these are based. The evidence is shown below (from mainstream journals only).
I believe that the minimum thing the current studies establish is that the people who developed and mastered these disciplines knew what they were doing and claiming and today there is a reasonable amount of compelling evidence to back of several of their claims.
Given this, is it really reasonable to summarily dismiss the rest of the claims that they have made about what are the experiences, results and conclusions when these paths are practiced intensely and with dedication for a whole lifetime? To call these things are results of self-delusion?
Let's face the fact that our current scientific understanding of how conscious subjective first person experience works is near zero. Yet, here is a set of traditions that have worked on this specific thing for thousands of years with dedication, expertise and effort and have reached some understanding of this using a set of practices that are clearly beneficial to us even in short bursts. So why not take them seriously and look further?
Note: Apologies in advance if I do not respond to everything and immediately. Real life is really busy. I will try to get to them I promise.
Note: This is the second thread on this topic from me. The previous threads responds to some common objections. See here

Physiological Effects of Yogic Practices and Transcendental Meditation in Health and Disease
Abstract
Yoga is an ancient Indian way of life, which includes changes in mental attitude, diet, and the practice of specific techniques such as yoga asanas (postures), breathing practices (pranayamas), and meditation to attain the highest level of consciousness. Since a decade, there has been a surge in the research on yoga, but we do find very few reviews regarding yogic practices and transcendental meditation (TM) in health and disease. Keeping this in view, a Medline search was done to review relevant articles in English literature on evaluation of physiological effects of yogic practices and TM. Data were constructed; issues were reviewed and found that there were considerable health benefits, including improved cognition, respiration, reduced cardiovascular risk, body mass index, blood pressure, and diabetes. Yoga also influenced immunity and ameliorated joint disorders.

Abstract
Background
This study examined the effects of brief daily yogic meditation on mental health, cognitive functioning, and immune cell telomerase activity in family dementia caregivers with mild depressive symptoms.
Results
The meditation group showed significantly lower levels of depressive symptoms and greater improvement in mental health and cognitive functioning compared with the relaxation group. In the meditation group, 65.2% showed 50% improvement on the Hamilton Depression Rating scale and 52% of the participants showed 50% improvement on the Mental Health Composite Summary score of the Short Form-36 scale compared with 31.2% and 19%, respectively, in the relaxation group (
p < 0.05). The meditation group showed 43% improvement in telomerase activity compared with 3.7% in the relaxation group (
p = 0.05).

The neuroscience of mindfulness meditation | Nature Reviews Neuroscience
Conclusions from the paper
- It is proposed that the mechanism through which mindfulness meditation exerts its effects is a process of enhanced self-regulation, including attention control, emotion regulation and self-awareness.
- Research on mindfulness meditation faces a number of important challenges in study design that limit the interpretation of existing studies.
- A number of changes in brain structure have been related to mindfulness meditation.
- Mindfulness practice enhances attention. The anterior cingulate cortex is the region associated with attention in which changes in activity and/or structure in response to mindfulness meditation are most consistently reported.
- Mindfulness practice improves emotion regulation and reduces stress. Fronto-limbic networks involved in these processes show various patterns of engagement by mindfulness meditation.
- Meditation practice has the potential to affect self-referential processing and improve present-moment awareness. The default mode networks — including the midline prefrontal cortex and posterior cingulate cortex, which support self-awareness — could be altered following mindfulness training.
- Mindfulness meditation has potential for the treatment of clinical disorders and might facilitate the cultivation of a healthy mind and increased well-being.
- Future research into mindfulness meditation should use randomized and actively controlled longitudinal studies with large sample sizes to validate previous findings.
- The effects of mindfulness practice on neural structure and function need to be linked to behavioural performance, such as cognitive, affective and social functioning, in future research.
- The complex mental state of mindfulness is likely to be supported by the large-scale brain networks; future work should take this into account rather than being restricted to activations in single brain areas.
