Bhagavad Gita is based, in the main , on Brahmanism. However, as an important Hindu scripture, it synthesizes yet remodifies the previous religious practices and thoughts. It is neo-Brahmanism in a sense that it reconstructs the Vedic tradition. However, the Gita does not totally succumb to the authority of the Veda and Brahmanic orthodoxy. On the one hand, it addresses to the general audience under caste system; on the other hand, it declares that any devotee of Krsna, irrespective of the position in caste system, has the chance to attain moksa. The first part of the thesis is on the meaning of karma in the Gita. The second part is on dharma, or rather svadharma. The third part is on the details classification of karma, that is , the idea of guna. The last part is on the encompassing idea of yoga in the Gita which embodies different yogin traditions. The above description also gives us an idea that from the 7th century BCE to the 3rd century AD Brahmanism faced many troubles within and without. Among others, the dissemination of Buddhism, Jainism and the rigor as well as possible disintegration of the caste system pose formidable challenges.
