Hindu synthesis

The Bhagavad Gita is the sealing achievement of the Hindu synthesis, incorporating its various religious traditions. The synthesis is at both philosophical and socio-religious levels, states the Gita scholar Keya Maitra. The text refrains from insisting on one right marga (path) to spirituality. It openly synthesizes and inclusively accepts multiple ways of life, harmonizing spiritual pursuits through action (karma), knowledge (jñāna), and devotion (bhakti). According to the Gita translator Radhakrishnan, quoted in a review by Robinson, Krishna's discourse is a "comprehensive synthesis" that inclusively unifies the competing strands of Hindu thought such as "Vedic ritual, Upanishadic wisdom, devotional theism and philosophical insight". Aurobindo described the text as a synthesis of various Yogas. The Indologist Robert Minor, and others, in contrast, state that the Gita is "more clearly defined as a synthesis of Vedanta, Yoga and Samkhya" philosophies of Hinduism.

The synthesis in Bhagavad Gita addresses the question of what constitutes the virtuous path that is necessary for spiritual liberation or release from the cycles of rebirth (moksha). It discusses whether one should renounce a householder lifestyle for a life as an ascetic, or lead a householder life dedicated to one's duty and profession, or pursue a householder life devoted to a personalized God in the revealed form of Krishna. Thus Gita discusses and synthesizes the three dominant trends in Hinduism: enlightenment-based renunciation, dharma-based householder life, and devotion-based theism. According to Eliot Deutsch and Rohit Dalvi, the Bhagavad Gita attempts "to forge a harmony" between these three paths.

The Bhagavad Gita ' s synthetic answer recommends that one must resist the "either-or" view, and consider a "both-and" view. It states that the dharmic householder can achieve the same goals as the renouncing monk through "inner renunciation" or "motiveless action". One must do the right thing because one has determined that it is right, states Gita, without craving for its fruits, without worrying about the results, loss or gain. Desires, selfishness, and the craving for fruits can distort one from spiritual living. The Gita synthesis goes further, according to its interpreters such as Swami Vivekananda, and the text states that there is Living God in every human being and the devoted service to this Living God in everyone – without craving for personal rewards – is a means to spiritual development and liberation. According to Galvin Flood, the teachings in the Gita differ from other Indian religions that encouraged extreme austerity and self-torture of various forms (karsayanta). The Gita disapproves of these, stating that not only is it against tradition but against Krishna himself, because "Krishna dwells within all beings, in torturing the body the ascetic would be torturing him", states Flood. Even a monk should strive for "inner renunciation" rather than external pretensions.

The Gita synthesizes several paths to spiritual realization based on the premise that people are born with different temperaments and tendencies (guna). Smith notes that the text acknowledges that some individuals are more reflective and intellectual, some are affective and engaged by their emotions, some are action-driven, yet others favor experimentation and exploring what works. It then presents different spiritual paths for each personality type respectively: the path of knowledge (jnana yoga), the path of devotion (bhakti yoga), the path of action (karma yoga), and the path of meditation (raja yoga). The guna premise is a synthesis of the ideas from the Samkhya school of Hinduism. According to Upadhyaya, the Gita states that none of these paths to spiritual realization is "intrinsically superior or inferior", rather they "converge in one and lead to the same goal".

According to Hiltebeitel, Bhakti forms an essential ingredient of this synthesis, and the text incorporates Bhakti into Vedanta. According to Scheepers, The Bhagavad Gita is a Brahmanical text which uses Shramanic and Yogic terminology to spread the Brahmanic idea of living according to one's duty or dharma, in contrast to the ascetic ideal of liberation by avoiding all karma. According to Galvin Flood and Charles Martin, the Gita rejects the Shramanic path of non-action, emphasizing instead "the renunciation of the fruits of action". The Bhagavad Gita, according to Raju, is a great synthesis of impersonal spiritual monism with personal God, of "the yoga of action with the yoga of transcendence of action, and these again with the yogas of devotion and knowledge". According to Catherine Cornille, the Gita presented the main beliefs of Hinduism, stressing upon the importance of detachment, duty, prevalence of gunas, difference between body and immortal soul, and its transmigration. The text assessed the paths of Jñāna, Bhakti, Karma, and Rāja yogas for the purpose of Moksha (spiritual liberation) and asserted that the path of Bhakti (devotion) is the foremost and the easiest of them all.
