You cannot do yoga.  Yoga is your natural state.  What you can do are yoga exercises, which may reveal to you where you are resisting your natural state.

Yoga is possible for anybody who really wants it.  Yoga is universal.... But don't approach yoga with a business mind looking for worldly gain.

~Sri Krishna Pattabhi Jois

Yoga is 99% practice and 1% knowledge.

Anyone who practices can obtain success in yoga but not one who is lazy.  Constant practice alone is the secret of success.

~Svatmarama, Hatha Yoga Pradipika

The meaning of our self is not to be found in its separateness from God and others, but in the ceaseless realization of yoga, of union; not on the side of the canvas where it is blank, but on the side where the picture is being painted.

Rabindranath Tagore

Yoga is the practice of quieting the mind. "Yogas Chitta Vritti Nirodaha"

Patanjali Yoga Sutra 1.2

Inhale, and God approaches you. Hold the inhalation, and God remains with you. Exhale, and you approach God. Hold the exhalation, and surrender to God.

Krishnamacharya

I practice now not so much with ambition as with gratitude. And I ask myself frequently, 'How can I express kindness right now?' whether I am in a headstand of washing dishes.

Judith Lasater

When you inhale, you are taking the strength from God. When you exhale, it represents the service you are giving to the world.

B.K.S. Iyengar

This yoga should be practiced with firm determination and perseverance, without any mental reservation or doubts.

Bhagavad-Gita

Yoga is really trying to liberate us from ... shame about our bodies. To love your body is a very important thing -- I think the health of your mind depends on your being able to love your body.

Rodney Yee

Before you've practiced, the theory is useless. After you've practiced, the theory is obvious.

David Williams, Ashtanga Instructor

Don't ask yourself what the world needs; ask yourself what makes you come alive. And then go and do that. Because what the world needs is people who have come alive.

Howard Thurman

The whole world is a single flower.

Sen Master Seung Sahn

The Self in you is the same as the Self Universal. Whatever powers are manifested throughout the world, those powers exist in germ, in latency, in you.... If you realize the unity of the Self amid the diversities of the Not-Self, then Yoga Will not seem an impossible thing to you.

Annie Wood Besant

You can enter yoga, or the path of yoga, only when you are totally frustrated with your own mind as it is. If you are still hoping that you can gain something through your mind, yoga is not for you.

Osho

The yoga mat is a good place to turn when talk therapy and antidepressants aren't enough.

Amy Weintraub

The state of severance of union with sorrow is known by the name of yoga.

Bhagavad Gita

The word yoga comes from Sanskrit, the language of ancient India. It means union, integration, or wholeness. It is an approach to health that promotes the harmonious collaboration of the human being's three components: body, mind, and spirit.

Stella Weller

Anyone who practices can obtain success in yoga but not one who is lazy. Constant practice alone is the secret of success.

Hatha Yoga Pradipika

The body is your temple. Keep it pure and clean for the soul to reside in.

B.K.S Iyengar

When the winds of change blow, some people build walls and others build windmills?
