Well spirituality is not enough for us, as creatures with the most fragile body that can stop functioning with a minor bug, what we really need to do first is have a healthy body.
Yoga helps with proper blood flow to all the organs, aids in digestion, respiration. It makes heart, kidneys, lungs healthier. So when you feel good, you do every task with happiness and good will. You end up enjoying even house chores. Taking out trash, loading dishes in dishwasher, doing laundry almost every routine mundane daily activities are somehow fun and never tire you. If you are stress free, your body cells regenerate fast. That actually makes yogis look ageless.
Your immunity peaks which helps you avoid diseases, even if you get one your body cures it rapidly. This happens because all your body organs are doing their job perfectly in sync. Yoga helps with mental purity too.
When a normal educated person looks at something, they apply all the logics and practicalities to it. When a yogi looks at the same thing, they see what it is, not exaggerated not imaginary just the reality of it. This comes from experience with practice.
Yoga helps people with anger issues. Yoga helps you balance life, if you drive a car but breaks don't work its of no use. You can run fast but you don't know when to stop. You are always working and you simply don't know how to pause and rest. You do have a lot of energy but somehow you are not using it well. You have earned a lot of money but instead of using it for charity you are stocking up. This is not life, If you are going for yoga and still stuck in all this, save yoga class money too.
Usually people pay way too much attention to their outer beauty but yoga makes you beautiful from inside, it gives you a beautiful heart mind body.
With yoga, clarity of thoughts comes, you become humble stable and kinder. Everyone looks beautiful to you.
Yoga brings discipline to your life. It creates excitement. Along with purity of thoughts and behavior, you start getting above minor things.
So if you want a healthy body, happy life, satisfaction, deep knowledge of universe practice yoga with full integrity.
