When someone is admitted to hospital, do you question protocols and procedures followed?
When someone enrolls in Army, is there any room for careless conduct?
When someone is preparing for Marathon, can non-discipline help?
Then why carelessness and pathetic ignorance about Yogic Practices?
Yoga is not exercise. If you are doing just Asana(s) or teaching Asana(s), call it aerobic exercise. Don’t call it Yoga. Yoga demands much more than mere exercise. Self-control & discipline in life are essential to begin Yogic Sadhana.
What do we do?
We eat junk in the evening and do Asanas in the morning! 
😀
We suffocate self while sleeping under AC close rooms and do Pranayama in the morning 😀
This will never help but on the other hand, it may work as contraindicated!
Self-proclaimed routine and life won’t work!
If you really want fruits of Yoga, learn and follow all prescriptions.
In brief the eight limbs, or steps to yoga, are as follows:
Yama : Universal morality
Niyama : Personal observances
Asanas : Body postures
Pranayama : Breathing exercises, and control of prana
Pratyahara : Control of the senses
Dharana : Concentration and cultivating inner perceptual awareness
Dhyana : Devotion, Meditation on the Divine
Samadhi : Union with the Divine
Consider it as westernization of eastern philosophy when philosophy is converted into catalog.
Yoga for men, Yoga for women, Yoga for morning, Yoga for night, Yoga for Chakra ….well save yourself from delusion!
नानारोगो भवेत्तस्य किञ्चिद्योगो न सिध्यति ॥१६॥He who practices Yogic exercises without moderation of diet, incurs various diseases, and obtains no success of any kind.
Moderation of diet is very important in Yogic exercises, dhyana or in any type of sadhana. If this is missed, success of any kind is not possible.
When Yogic exercises are performed as just another way of aerobic exercise, we not only incur any benefit but also damage body severely.
