Yoga is not a sedative. Its an invigorating force.
One must have patience and faith in the Guru (teacher).
One can start yoga and meditation at any time in their life after understanding the basic fundamentals.
Stillness is the highest level of intensity. When there is stillness within you, your body, mind, and energies will be exuberantly intense.
Experience of the self is the first stage which is followed by the second stage that is one of complete visualization and transcendence
The meditation approach is based on understanding of total personality and cure and not the symptoms alone.
Biologically and physiologically, the subconscious human brain is similar to the animal brain. It runs on preset patterns. The higher layer of brain tissue available to humans is the conscious brain, which provides the realization to free will and choice. If this higher faculty is not used to become more conscious of the higher aspects of life, it is taken away in the next lifetime.
Karmically, to have animals killed en mass in slaughterhouses creates such heavy Karma that it is paid by having humans slaughtered en mass in wars.
Killing plants/vegetables also is an act creating Karma. The protection from the reaction comes by offering those vegetables to the Supreme Person with love. Then the reaction (karmic) to the act is eliminated.
Yoga has been found to be efficacious in: Smoking and Alcohol dependence: Substance Dependence (Bowen et.al 2007), Anxiety and Tension / Stress (Burkett et al, 2006, Lee, 2007, Lindberg, 2005), Insomnia and Epilepsy (Yardi, 2001). Psoriasis, Chronic low back pain (LBP) (Williams, 2005). Immunity (Lindberg, 2005, Roggia, 2001), Cardiac diseases, Asthma/ COPD, Eating Disorders, Depression/ Dysthymia (Lindberg, 2005;Galantino, 2003, Pilkington,2005). Adjunct to Infertility Treatment (Khalsa, 2003; Khalsa, 2004). Chronic Fatigue syndrome, Psychosomatic disorders (Galantino, 2003). Perimenopause/ Menopause (Cohen et al.2007), Prostrate cancer, Carpal-tunnel syndrome (Garfinkel, 1998), ect..
The most important rationale is the growing acceptance of utilizing the human self-regulatory capabilities for the treatment of psychosomatic diseases. Yogic approaches are the prime example of such human self-regulatory capacities (Singh, 2006).
