Yoga ( ; Sanskrit, योगः Listen) is a group of physical, mental, and spiritual practices or disciplines which originated in ancient India.
 There is a broad variety of yoga schools, practices, and goals in Hinduism, Buddhism, and Jainism.
 Among the most well-known types of yoga are Hatha yoga and Rāja yoga.
Karma yoga, also called Karma marga, is one of the several spiritual paths in Hinduism, one based on the "yoga of action".
 To a "karma yogi", right work done well is a form of prayer.
 It is one of the paths in the spiritual practices of Hindus, others being Raja yoga ,Jnana yoga (path of knowledge) and Bhakti yoga (path of loving devotion to a personal god).
 The three paths are not mutually exclusive in Hinduism, but the relative emphasis between Karma yoga, Jnana yoga and Bhakti yoga varies by the individual.
Bhakti yoga, also called Bhakti marga (literally the path of "Bhakti"), is a spiritual path or spiritual practice within Hinduism focused on loving devotion towards a personal god.
 It is one of the paths in the spiritual practices of Hindus, others being Jnana yoga and Karma yoga.
 The tradition has ancient roots.
 Bhakti is mentioned in the "Shvetashvatara Upanishad" where it simply means participation, devotion and love for any endeavor.
 "Bhakti yoga" as one of three spiritual paths for salvation is discussed in depth by the "Bhagavad Gita".
Om (   , IAST: "Auṃ" or "Oṃ", Devanagari: ॐ ) is a sacred sound and a spiritual icon in Hindu religion.
 It is also a mantra in Hinduism, Buddhism, Jainism, and Sikhism.
Swami Sivananda's approach to yoga was to combine the four main paths - karma yoga, bhakti yoga, jnana yoga and raja yoga along with various sub-yogas such as kirtan and hatha yoga.
 This is reflected in the motto of the society that he formed, the Divine Life Society.
 The motto says, "Serve (Karma Yoga), Love (Bhakti Yoga), Meditate (Jnana Yoga), Realise (Raja Yoga)."
 In his own words, "One-sided development is not commendable.
 Religion and Yoga must educate and develop the whole man - his heart, intellect and hand."
Jñāna yoga, also known as Jnanamarga, is one of the several spiritual paths in Hinduism that emphasizes the "path of knowledge", also known as the "path of self-realization".
 It is one of the three classical paths ("margas") for moksha (salvation, liberation).
 The other two are karma yoga (path of action, "karmamarga") and bhakti yoga (path of loving devotion to a personal god, "bhaktimarga").
 Later, new movements within Hinduism added raja yoga as the fourth spiritual path, but this is not universally accepted as distinct to other three.
Pranava yoga is meditation on the sacred mantra Om, as outlined in the Upanishads, the "Bhagavad Gita", and the "Yoga Sutras of Patanjali".
 It is also called "Aum yoga" and "Aum yoga meditation".
 It is, simply put, fixing the mind on the sound of the mantra “Aum” – the sacred syllable that both symbolizes and embodies Brahman, the Absolute Reality – as the mantra is constantly repeated in unison with the breath.
 The purpose of pranava yoga is to become free from suffering and limitation.
