BG Chap 8 - The pure devotee as different from the yoga-misra-bhakta
The Supreme person, within whom exists all entities, who is all pervading, is attained by unalloyed devotion. He can be attained easily by pure bhakti but difficult to attain by bhakti mixed with aṣṭāṅga-yoga. Maintaining desires for jñāna, karma, yoga and so on prevents us from attaining Kṛṣṇa.
The pure devotee remembers the Lord at all times without deviation to other processes such as karma yoga or aṣṭāṅga yoga or goals such as Svarga or liberation. He constantly desires association with the Lord in one of the primary relationships and easily attains the Lord. Thru such processes as japa and deity worship, every day continually, without regard for time, place or purity, he remembers the Supreme Lord, who drinks the breast milk of Yaśodā and who appears in this world in many forms. He attains the Lord easily not encountering the difficulties in karma yoga and aṣṭāṅga-yoga or other processes. The Lord is the cause or the doer of the pure devotee attaining Him. The Lord cannot tolerate separation from the devotee and thus shows Himself to the devotee. He is easy to attain for the devotee because He destroys the obstacles and perfects the devotee’s sādhana. Kṛṣṇa gives the devotee the knowledge by which the devotee attains Him (BG 10.10). This devotee is related to the Lord (yoga) in dāsya, sakhya or other rasas. A vivid example of ananya-cetā-bhakti is found in Caitanya-līlā, when the Lord was advised by a small boy Gopāla that Kṛṣṇa’s names are pure and should be chanted always regardless of the external purity of the situation.
