Included is a foreword on the life and teachings of Swami Satyadharma, who passed away while writing the commentary on Dhyānabindu. Her commentary on Nādabindu is complete. The Dhyāna and Nādabindu Upaniṣads were probably composed between the ninth and fourteenth centuries CE. The bindu is a psychic centre located in the brain at the top back of the head. These upaniṣads focus on meditation on the bindu, the source point or origin of individual creation, where begins the primal sound or first vibration, the mantra Om. They define and describe in detail the mantra Om, the effects of meditating on it until one attains perfect liberation, merging with the Divine.Nādabindu describes the components of Om, that is, its three and a half measures (mātrā) which are the sounds a u m, and the half measure, the echo of m. Always meditating on Om, the yogin is liberated from worldly life, unaffected by his/her karmas. The nāda is first heard through the right ear, and many other inner sounds are heard. Eventually the yogin hears no other sounds and transcends duality.Dhyānabindu, an expansion of Nādabindu, confirms that meditation on Om can destroy all karmas. The yogin should meditate on the lotus of the heart, then at the eyebrow centre, then on the Sun, Moon and Agni, leading to the ātman. The six parts of yoga, the cakras, nāḍīs and prāṇas are described. Kuṇḍalinī Śakti can be awakened by the repetition of the mantra haṃsa, ham spontaneously accompanying the inhalation, and sa the exhalation, as well as uḍḍiyāna and jālandhara bandhas, khecarī mudrā and mahāmudrā. The ātman is described in detail. Finally, the teacher recommends meditating on the bija mantras of the five elements, the five prāṇas and the nāda.

Aims to serve as a manual of higher sadhana for advanced and initiated aspirants. This title describes the ancient path of Kundalini awakening in its original form before the proliferation of modern Yogic literature.

Yoga Kundalini Upanishad is arranged in three parts. Chapter one contains the yogic physiology of kuṇḍalinī and the requisite disciplines necessary to undertake her activation and awakening. Chapter two contains an exposition of the important practices of khecarī mudrā and sūtra neti. Chapter three contains more specific instructions on how to maintain a higher sādhana, including meditation practices on sound and Soham, on the ātman, spontaneous jñāna yoga, and merging with the ātman. Finally the master tells how to become a supreme yogī.Included in the text are the original Sanskrit verses, transliteration, word meanings, translation and a comprehensive commentary by Swami Satyadharma Saraswati.

Shandilya Upanishad is the sixth volume of the Yoga Upanishads series. The Śāṇḍilya Upaniṣad is connected with the Atharva Veda. It commences with the yogin invoking Rāma to guide him along the eightfold path of yoga to liberation.In the first verse of chapter one, Śāṇḍilya asks Atharvan to instruct him in the eight limbed path of yoga, with the aim of reaching the true Self. Śāṇḍilya himself was a Rishi with many disciples, and was the progenitor of the Śāṇḍilya lineage. Atharvan was a Vedic rishi, who, together with Angiras, is said to have revealed the Atharva Veda, and was the first to perform yagña, fire oblations. The first two sections describe the foundations of yoga, yama and niyama, external and internal restraints. Section three describes the eight āsanas, which, as well as having physical, mental and energic benefits, prepare the body for sitting still for a long time in meditation without discomfort.Later sections describe the fourteen main nāḍīs, ten vāyus, maṇipura cakra and kuṇḍalinī of the subtle or pranic body. The methods of purification of the nāḍīs are described in great detail, as purification is considered necessary for the higher stages of concentration (dhāraṇā) and meditation (dhyāna). The prerequisites for yoga practice are listed. A meditation on agni maṇḍala is given. Prāṇāyāma is defined as AUM, and the practice of nāḍī śodhana prāṇāyāma with emphasis on kumbhaka and the effects of the practice are described in detail.Teachings are then given on khecarī and vaiṣṇavī mudrā, control of prāṇa, awakening kuṇḍalinī, saṃyama, pratyāhāraḥ, dhāraṇā, dhyāna and samādhi. The necessity of both yoga and jñāna for liberation is emphasised.Chapter two has sections on knowledge of Brahman, creation of the universe, the names of Brahman, and Dattātreya.

This unique book explains in great detail the esoteric concept of 'OM/Aum' and 'Naad' as they are envisioned and elucidated by the Upanishads. All the various connotations and aspects of 'OM' as well as the 'Naad' are elaborately dealt with. While 'OM/Aum' is a monosyllabic word that represents the cosmic Supreme Consciousness that is all-pervading and is at the core of the entire living creation, the 'Naad' is the sound created by the vibration that this Consciousness produces in the vast realm of the cosmos. The 'Naad', the cosmic Sound, is the first and subtlest manifestation of life created by the Supreme Consciousness in all its myriad forms, from the most primitive to the most advanced. The 'OM' is a means to realize this Consciousness.

Modern science and ancient wisdom traditions agree that the universe is a symphony of vibrational frequencies. In this comprehensive work, the author elaborates the essential truths about cosmic sound, and how we can employ important mantras for healing, transformation and inner awakening.
