God is always full and complete; to reach such infinite fullness you must have full faith. When God is full and complete and you are not full and complete, there cannot develop the necessary binding force that will hold you and God together. To reach the full and complete love that is God, you must also have a full heart, full of love and faith. If, instead, you are filled with doubts, you will undermine this pure principle of love which is your true nature; your doubts will blemish your heart and distance you from the omniscient, omnipotent and omnipresent Lord, who is aware of your every thought.
Whatever thoughts you have, fill them with him. Think of him with a full heart saturated with love and faith; then you will certainly reach him. In the Gita, He said that you will become dear to him when you worship him fully with all your heart. That means seeing him everywhere, in everything. The Gita proclaimed, in all of the creation do not hate anyone or anything, for he is in every name and form. When you have the feeling of love permeating your whole being, you become very dear to him.
All the noble human qualities are already there in their fullness in every human being, but very few people are making any effort to become aware of them. They are wasting their time in pursuing only outer activities in the world. But you must also engage in inner activities which will help you to reach your goal. For example, you perform your worship using external rituals, but you must perform your worship internally, as well, offering God the flowers of your heart. Then there will be unity and harmony in your life. Once you achieve such unity in all your activities, both inner and outer, your life becomes sanctified and you will experience fulfillment in whatever you do.
