According to Crangle, some researchers have favoured a linear theory, which attempts “to interpret the origin and early development of Indian contemplative practices as a sequential growth from an Aryan genesis”, just like traditional Hinduism regards the Vedas to be the ultimate source of all spiritual knowledge.
Ascetic practices (tapas), concentration and bodily postures used by Vedic priests to conduct yajna (sacrifice), might have been precursors to yoga.
Early Samhitas also contain references to other group ascetics such as munis, the keśin, and vratyas. Techniques for controlling breath and vital energies are mentioned in the Brahmanas.
The brain and gut are in constant communication via the vagus nerve. Which is why gut health and mental health are intrinsically linked. Actually, research shows that when it comes to people with food sensitivities, anxiety, gut problems, brain fog.
Having a good balance of healthy gut bacteria has been shown in numerous studies to positively affect the vagus nerve and contribute to better brain health. If you suffer with digestive issues – reflect upon whether these bouts of indigestion or stomach issues tend to be accompanied by mood swings or brain fog. If the answer is ‘yes’, it’s time to take greater care of your gut, as over 80% of our immune system.
Taking a good quality probiotic can help improve gut bacteria, as can including more pre and probiotics in your meals – think sauerkraut, kimchi, kombucha or kefir. Practices like occasional fasting, ensuring you’re not eating too late at night, and cutting down on refined sugar can also have a positive impact upon gut health.
