Bhakti-lata-bija means "the seed of devotional service." Everything has an original cause, or seed. For any idea, program, plan or device, there is first of all the contemplation of the plan, and that is called bija, or the seed. The methods, rules and regulations by which one is perfectly trained in devotional service constitute the bhakti-lata-bija, or seed of devotional service. This bhakti-lata-bija is received from the spiritual master by the grace of Krsna. Other seeds are called anyabhilasa-bija, karma-bija and jnana-bija. If one is not fortunate enough to receive the bhakti-lata-bija from the spiritual master, he instead cultivates the seeds of karma-bija, jnana-bija, or political and social or philanthropic bija. However, bhakti-lata-bija is different from these other bijas. Bhakti-lata-bija can be received only through the mercy of the spiritual master. Therefore one has to satisfy the spiritual master to get bhakti-lata-bija (yasya prasadad bhagavat-prasadah). Bhakti-lata-bija is the origin of devotional service. Unless one satisfies the spiritual master, he gets the bija, or root cause, of karma, jnana and yoga without the benefit of devotional service. However, one who is faithful to his spiritual master gets the bhakti-lata-bija. This bhakti-lata-bija is received when one is initiated by the bona fide spiritual master. After receiving the spiritual master's mercy, one must repeat his instructions, and this is called sravana-kirtana-hearing and chanting. One who has not properly heard from the spiritual master or who does not follow the regulative principles is not fit for chanting (kirtana). This is explained in Bhagavad-gita (2.41): vyavasayatmika buddhir ekeha kuru-nandana. One who has not listened carefully to the instructions of the spiritual master is unfit to chant or preach the cult of devotional service. One has to water the bhakti-lata-bija after receiving instructions from the spiritual master.
