To unite with Him in the end, one must devote one's mind and feelings to Him. To submit your mind to God, one must understand the essence and secrets of His virtues, influence and power; and keep them in his resolve always and everywhere. To immerse your feelings Him and Him alone and nothing else one must detach oneself from all objects of senses; and at all times of only Him.
However, due to attachments resulting from ignorance men are involved in attachments to worldly objects and hence are unable to perform the exercise above.
Since not everybody has the same nature, they can't unite with Him using the same method. For different kinds of men there are different ways to achieve God.
If you can't devote your mind and feelings to Him do not despair. One who tries can also obtain Him. In whatever form of God you have the most faith and love for, you must try to devote your mind to that form. There are various means to do this and some of the most appropriate ones for common man are the following:
- You must resolve to make an effort to devote your mind and feelings to God.
- You must try to see God wherever your mind goes and whatever your eyes see and hence think about him.
- You must try to steer your mind away from all other objects and concentrate on the idol/picture of the form of God that you love the most.
- Chant "Omkar" and meditate.
- You must try to chant his name as often as possible.
- You must try to read scriptures again and again to understand the essence of his virtues, influence and power
- Perform pranayama.
Any of the above performed with true faith and love will clear you of your sins, destroy all the hurdles and lead you to God. If one doesn't obtain results soon then one must not loose heart. Instead, try with increased effort.
If all the above exercises are beyond you, then all you have to do is perform every action for God and for nothing else. Behind every action of yours, there should be no self-interest, no attachment and no sense of ownership. Perform every action from your heart and to please the God; serve God through your mind, speech and actions; perform yagya, make donations and do prayers - all in the name of God and as your duty towards him.
If you think that it is difficult for you to selflessly perform every action, then all you need to do is take control over your mind and feelings and sacrifice the fruits of your actions. If you don't have control over your mind and feelings, then you'll be entrapped in indulgences and when this happens one can't escape from the desire to indulge in the fruits of one's actions. These actions include the rituals that you perform, the donations that you make, the prayers and service that you and all other actions performed as part of your duty or for your body to survive. Relinquish any attachment, any sense of ownership and any interest in the results of these actions. The actions do not include such actions as stealing, lying, infidelity, violence or any action not sanctioned by the scriptures because these are the actions that result from a man's attachment and sense of ownership.
