According to Deutsch and Dalvi, the Bhagavad Gita attempts "to forge a harmony" between different strands of Indian thought: jnana, dharma and bhakti. Deutsch and Dalvi note that the authors of the Bhagavad Gita "must have seen the appeal of the soteriologies both of the "heterodox" traditions of Buddhism and Jainism and of the more "orthodox" ones of Samkhya and Yoga", while the Brahmanic tradition emphasised "the significance of dharma as the instrument of goodness". Scheepers mentions the Bhagavat Gita as a Brahmanical text which uses the shramanic and Yogic terminology to spread the Brahmanic idea of living according to one's duty or dharma, in contrast to the yogic ideal of liberation from the workings of karma. According to Basham,
The Bhagavadgita combines many different elements from Samkhya and Vedanta philosophy. In matters of religion, its important contribution was the new emphasis placed on devotion, which has since remained a central path in Hinduism. In addition, the popular theism expressed elsewhere in the Mahabharata and the transcendentalism of the Upanishads converge, and a God of personal characteristics is identified with the brahman of the Vedic tradition. The Bhagavadgita thus gives a typology of the three dominant trends of Indian religion: dharma-based householder life, enlightenment-based renunciation, and devotion-based theism.
The Bhagavadgita may be treated as a great synthesis of the ideas of the impersonal spiritual monism with personalistic monotheism, of the yoga of action with the yoga of transcendence of action, and these again with yogas of devotion and knowledge.
