Tirumalai Krishnamacharya quotes:

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.

Nowadays, the practice of yoga stops with just asanas. Very few even attempt dharana and dhyana (deeper meditation) with seriousness. There is a need to search once more and reestablish the practice and value of yoga in modern times.

Let your speech be true and sweet.

Rid your body of its impurities, let your speech be true and sweet, feel friendship for the world, and with humility seek wealth and knowledge.

In the practice of Yoga one can emphasize the body, the mind or the self and hence the effort can never be fruitless.

Master your breath, let the self be in bliss, contemplate on the sublime within you.

Meditation results in marvels.

No one is wise by birth, for wisdom results from one own's efforts.

Regulate the breath, be happy, link the mind with the Lord in your heart.

Knowing all objects to be impermanent, let not their contact blind you, resolve again and again to be aware of the Self that is permanent.

Never be in debt. Never reside near enemies. Never trap your body through disease. Never forget the Lord with his consort who resides in the heart.

Teach what is inside you. Not as it applies to you, to yourself, but as it applies to the other.

Where is the delusion when truth is known? Where is the disease when the mind is clear? Where is death when the Breath is controlled? Therefore surrender to Yoga.

Why do we need money beyond a point? If we are free of ill health, enmity, and debt, is that not enough? Too much money only leads to less peace.
