" Nishkama karma (nish = without - kama = desire, karma=action) An action performed without a wish or desire for the 'fruits' or results of such action. The ultimate yogic ideal is to perform all actions without desire for personal gain, and to offer instead the fruits of all actions to God.
Performing actions with the mind directed toward results increases ego and keeps us bonded to the idea of I and Mine, while offering the fruits of actions to God leads toward surrender to the divine will and liberation from the idea of a separate self."

"The phrase Universal Self is a translation of the word Atman. According to Vedanta, the Atman is the soul of man, and all souls are part of an infinite, all-pervading Supreme Spirit.
The Supreme Self/Universal Self/Indwelling Spirit or just Self refers to our higher, unchanging, eternal nature of pure consciousness, truth and bliss."

"The way of establishing the mind in the Self should be known as yoga.
Yoga chitta vritti nirodhaha Yoga is the process of ending the definitions of the field of consciousness."

"By the strength gained through this practice, we can come to know the method for bringing the mind and sense organs under control. Thus can we achieve yoga. For it is only through the control of the mind and sense organs that we come to know our true nature, and not through intellectual knowledge, or by putting on the garb of a yogi."

"How can we make the mind one-pointed so that we may see the Universal Self? This is what Ashtanga Yoga teaches. The word Ashtanga means eight limbs, or steps, and these comprise:
Yama
Niyama
Asana
Pranayama
Pratyahara
Dharana
Dhyana
Samadhi

The original teachings of Ashtanga Yoga Master Sri K. Pattabhi Jois.

Yoga:
It's aim is the purification of the mind and body. It's a perfect way of life. It is an ethic, discipline, and path of spiritual life.
(Prof. N.A.Nikam)

This book is a must for students of Ayurveda. In addition, modern physicians specializing in the treatment of mental illness will undoubtly find it useful.
(M. Yamunacharya)

The parampara of Rama Mohan Brahmachari and Sri T. Krishnamacharya carried on with Patthabi Jois (Guruji).
Beyond asanas, there are the observances of yama and niyama - how we conduct ourselves with the world in a kind and aware manner, and how we abide by our own code of morality.

The unique aspect of Krishnamacharya's teaching was vinyasa karma, the systematic method of linking breath and movement.
R. Sharath)

In the sacret text of the yogis, the Bhagavad Gita, Krishna proclaims that one comes to yoga in this life only by having practiced it in a previous life, and is pulled toward it against one's will, as toward a magnet.
Guruji taught without hesitation, neither for fame nor money, although these things may have come to him. Pattabhi Jois was a shining example of pure dedication, of what it takes to keep the light of an ancient tradition burning brightly.
(Eddie Stern)

Some people even have a fear of practicing it altogether. But this is little different from the opinion of those who look for the faults of sugar without knowing its sweetness. Once they taste it, its sweetness becomes apparant. Similarly, once we practice yoga, we come to realize its ananda (bliss).
And yet the practice of yoga still leaves us subject to doubts and misconceptions, which weaken our minds and sense organs.
If we practice the science of yoga, which is useful to the entire human community and which yields happiness both here and hereafter - if we practice without fail, we will then attain physical, mental and spiritual happiness, and our minds will flood toward the Self.
(K. Pattabhi Jois).
