Kshatriyas put the revolutionary karma discourse forward to the Brahmins. Maybe the Kshatriyas did the same with yoga. In other words the Yajur-veda Brahmin branch were exposed to an intensive debate with their fellow power-sharing Kshatriyas, who on their side were influenced by the strong Sramana movement in that area.
The Upanishads were often composed as dialogues between a sage and a novice. However as we saw earlier the sage was in many cases not a Brahmin. Instead the Brahmins were often portrayed as perplexed and misled. The expert in the teachings was often a Kshatriya – frequently in the form of a king. Hence we hear about Kshatriya sages like Janaka, Asvapati, Pravahana and Ajatasatru. This could of course only signify a narrative twist, but I find it signifies a real process. Why?
The Kshatriyas were, as mentioned earlier, a highly educated class who were perceived as possessing superior knowledge’ and were able to teach the Vedas (Chatterji 2007). It was two Kshatriyas who founded the two revolutionary new religio-philosophies of Buddhism and Jainism: Buddha and Mahavira. And we can see for certain that the Buddha was highly educated and was even well versed in the Vedas and Brahmin philosophy (Gombrich 2009). Thus it is not unlikely that similar Kshatriya sages could have engaged the Brahmins with new yoga ideas.
In a 12-week double-blind, randomized placebo Parsvakonasana Yoga Pose -controlled DBRPC trial, 56 patients with treatment resistant schizophrenia were given ginkgo 360 mg/ Parsvakonasana Yoga Pose day plus haloperidol 1/4 mg/kg/day and compared with 53 patients given placebo plus haloperidol 1/4 mg/kg/day. The ginkgo group showed greater improvement in positive and negative symptoms. Furthermore, 57% of the patients in the ginkgo group were rated as responders versus 38% of the placebo group. The rate of extrapyramidal symptoms EPS was less in the ginkgo group Zhang, Zhou, Zhang, Wu, Su et al., 2001. Positive symptoms of schizophrenia include delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior. Negative symptoms refer to flattening of affect, alogia restriction in the fluency and productivity of thought and speech, and avolition restriction in goal-directed behavior. A double-blind, randomized controlled trial DBRCT evaluated the ability of ginkgo EGb to augment the effects of olanzapine.
