When we take initiation we promise to the spiritual master, the fire, Paramatma, the Vaishnavas and other witnesses, to chant the holy name of the Lord, to follow the principles. We promise to practice and propagate Krishna consciousness, and a promise to stay in ISKCON for the rest of our life, to stay loyal and active within the Hare Krishna movement.
So once we get the bhakti lata bija, we want to make sure that the bija doesn’t remain just a bija- a seed all the time. That seed has to sprout. From the seed comes the seedling and then it has to grow in the land, becomes a bush before it turns into a tree and finally you could pick up some fruits of love of Godhead.
