Notes
Prologue: The Journey
1   The Latin homo derives from an Indo-European root for “earth”, and has the sense of “earthling”. It is usually translated as “man” or “human”. Sapiens means “wise” or “knowing”. Homo sapiens sapiens is the name of our sub-species.
2   The Bhagavad Gita forms part of “The Book of Bhishma”, the sixth book of the Mahabharata, or great tale of the Bharata dynasty. The Mahabharata is the longest poem ever written, with about 1.8 million words. The text predates Christ, with references to it found as early as the 4th century BCE. According to archaeoastronomy, the events of the Mahabharata unfold some 5,000 years ago.
3   The traditional colophon that ends each chapter of the Bhagavad Gita identifies the text as an Upanishad on yoga. In the original Sanskrit text, the word yoga appears 78 times as a noun and 36 times in its verbal form as yukta, while the word yogi appears 28 times. In using the term yoga, the Gita doesn’t refer solely to teachings similar to those recommended by Patanjali in his Yoga Sutra, but adopts a far broader usage.

5   The Bhagavad Gita is often referred to as Gitopanishad, indicating its equal status with the Upanishad texts of the Vedas. The Gita-mahatmyam (verse 6) of Shri Shankaracharya describes the Gita as the essence of all the Upanishads. This makes the Gita the essence of the Vedas. The Gita is one of the three canonical texts of Indian philosophy (known collectively as the prasthana-traya, the three foundations), especially for the Vedanta schools.
6   For example, the Brihad-aranyaka Upanishad (4.4.21) distinguishes between perfect knowledge (prajna), which manifests in action, and the knowledge of books, which it describes as “mere weariness of the tongue”.
7   Bhagavad Gita, 4.2.
8   Bhagavad Gita, 4.34: tattva-darshinah (“truth seer”).
9   Stick-Like Prostration is similar to Shavasana, or “Corpse Pose”, a yoga posture that normally comes at the end of a yoga session. Corpse Pose represents saying yes to life, allowing what is to be. Stick-Like Prostration is also a pose of surrender, but is imbued with the beautiful qualities of deep humility, dedication and devotion.

11   The Sanskrit term yoga derives from yujir, meaning “to unite” or “to connect” (yujir yoge), as well as from yuj in the sense of stilling (yuj samyamane) and of enlightenment (yuj samadhau). In the Bhagavad Gita, the word yoga is used in varied ways, but these all derive directly or indirectly from the sense of yoking, uniting or connecting. See Surendranath Dasgupta, Philosophical Essays (1982), pp. 89–91.
12   Bhagavad Gita, 2.50: “yoga is skill in action” (yogah karmasu kaushalam).
13   Each of the Bhagavad Gita’s eighteen chapters is traditionally named according to the specific system of yoga it sets out. There are no chapter titles in the original text of the Gita or in the Mahabharata, for that matter, but over time similar or identical titles have been assigned consistently to its chapters. Chapter 1 is commonly entitled arjuna-vishada-yoga, “The Yoga of Arjuna’s Despair”. Arjuna’s dark night experience, while painful and highly disorientating, simultaneously creates the opportunity for his inner transformation and spiritual deepening. By studying Arjuna’s despair and how he emerges from it, we engage in a process of yoga ourselves.
14   For instance, Narada’s despair led to Sanat-kumara’s profound teachings in the ancient Chandogya Upanishad. Narada had a student named Vyasa. At the height of his literary accomplishments, Vyasa was consumed by a feeling of utter emptiness. His teacher, Narada, guided him out of his dark night. The result was the Bhagavata Purana, a twelve-volume work of astonishing beauty. Then, the despair of Narada’s student Valmiki led to the Ramayana, one of India’s great epics, made up of nearly 24,000 verses.
15   This is illustrated by Arjuna’s dark night of the soul in the Bhagavad Gita, which is characterised not just by outer difficulty, but above all by inner conflict. Arjuna’s outer crisis is described in verses 1–27 of Chapter 1, while his inner crisis is described in verses 28–47.
16   St John of the Cross (1542–1591) was a Spanish mystic in the Carmelite order. Born in Fontiveros, near Ávila, he composed a poem entitled Dark Night of the Soul (La noche oscura del alma) during his own dark night experience in 1578 or 1579, while imprisoned for trying to reform the Carmelite order. St John was held in isolation and darkness in a tiny stifling cell barely large enough for his body, and was subjected to brutal public lashing at least weekly. St John also wrote a commentary on this poem by the same name in 1584–85. His poetry and studies on the growth of the soul are widely regarded as masterpieces and the summit of mystical Spanish literature. For further details about St John’s life, see Richard P. Hardy, John of the Cross: Man and Mystic (2004).
17   The Rig Veda, for instance, states, “Truth is one, though the learned speak of it in many ways” (1.164.46). The Bhagavata Purana similarly advises (11.8.10), “As the honey-bee extracts nectar from all flowers, big and small, a discriminating person should take the essence from all sacred texts.”
18   Indeed, this represents a key distinction between Patanjali’s Yoga Sutra and the Bhagavad Gita. The Yoga Sutra offers prescriptions especially suited for ascetics, who have disengaged from the world. Often naked and strangely adorned to assert their freedom from social stricture, Indian ascetics are commonly wanderers. They frequently take vows of silence and may retreat to isolated hideouts in the jungle, desert or mountains. By contrast, the Gita offers yoga teachings directed specifically at those who are in active engagement with the world, like Arjuna.
19   Bhagavad Gita, 13.10: bhaktir avyabhicharini, “the unwavering offering of love”. Krishna advises Arjuna to pursue no other form of yoga.
