Karma yoga 11.20 of the "Bhagavata Purana" states that there are only three means to spiritual liberation: "jnana yoga" (knowledge), "karma yoga" (action) and "bhakti yoga" (devotion). Those who are of philosophical bent, prefer the "knowledge path". Those who are inclined to productive application of arts, skills and knowledge, prefer the "karma path". Those who prefer emotional connection, prefer the "devotional path". These three paths overlap, with different relative emphasis. Discussions on Karma yoga are also found in chapter 33 of "Narada Purana". Later, new movements within Hinduism added raja yoga as the fourth spiritual path, but this is not universally accepted
Bhakti movement concept of the Ultimate Reality as formless, without attributes or quality. "Saguna" Brahman, in contrast, was envisioned and developed as with form, attributes and quality. The two had parallels in the ancient pantheistic unmanifest and theistic manifest traditions, respectively, and traceable to Arjuna-Krishna dialogue in the Bhagavad Gita. It is the same Brahman, but viewed from two perspectives, one from "Nirguni" knowledge-focus and other from "Saguni" love-focus, united as Krishna in the Gita. "Nirguna" bhakta's poetry were "Jnana-shrayi", or had roots in knowledge. "Saguna" bhakta's poetry were "Prema-shrayi", or with roots in love. In Bhakti, the emphasis is reciprocal love
