Pancham Sinh, translator, The Hatha Yoga Pradipika (New Delhi: Munshiram Manoharlal, 2007) ("The Asanas are a means of gaining steadiness of position and help to gain success in contemplation, without any distraction of the mind. If the position be not comfortable, the slightest inconvenience will draw the mind away from the laksya (aim), and so no peace of mind will be possible till the posture has ceased to cause pain by regular exercise." Id. at iv. "Whether young, old or too old, sick or lean, one who discards laziness, gets success if he practices Yoga." "Success comes to him who is engaged in the practice. How can one get success without practice; for by merely reading books on Yoga one can never get success." "Success cannot be attained by adopting a particular dress (Vesa). It cannot be gained by telling tales. Practice alone is the means to success, This is true, there is no doubt." Id. at 11. "Mind is the master of the senses, and the breath is the master of the mind. The breath in its turn is subordinated to the laya (absorption), and the laya depends on the nada." Id. at 51. "Freeing the mind from all thoughts and thinking of nothing, one should sit firmly like a pot in the space (surrounded and filled with the ether). Id. at 54. "One should become void in and void out, and void like a pot in the space. Full in and full outside, like a jar in the ocean." "He should be neither of his inside nor of outside world; and leaving all thoughts, he should think of nothing." "The whole of this world and all the schemes of the mind are but the creations of thought. Discarding these thoughts and taking leave of all conjectures, O Rama! obtain peace." "When the knowable, and the knowledge , are both destroyed equally, then there is no second way (i.e., Duality is destroyed). Id. at 55. "He whose mind is neither sleeping, waking, remembering, destitute of memory, disappearing nor appearing, is liberated." Id. at 62.).
Michael Roach (with the Diamond Mountain Teachers), The Tibetan Book of Yoga: Ancient Buddhist Teachings on the Philosophy and Practice of Yoga (New York: Doubleday, 2003) ("The ancient art of yoga came to Tibet from its birthplace in India over a thousand years ago. It quickly became very popular, and wonderful systems for its practice sprang up like mushrooms all over the country. The yoga practice you will learn here, which is called Tibetan Heart Yoga, belongs to the Gelukpa tradition of the Dalai Lamas of Tibet." "Tibetan Heart Yoga works on your heart in two ways: It makes your physical heart and body healthy and strong, and it opens your heart to love others. And of course, really the first always comes from the second." Id. at 1-2.).
