In the pursuit of Enlightenment or spiritual practice, whatever you may want to call it, your attitude and your identity matters. You currently identify yourself with the body and the mind. However, you may intellectually understand that you are also the spirit or the Self. At different times, you identify with different aspects of your self. You may at times identify with the body and yet at other times get carried away by the thoughts and identify with the mind and yet at other times on introspection, briefly identify with the deeper aspect of your being.
As an analogy, let us look to the famous Indian Epic called the Ramayana. In it, the character, Rama, who represents the eternal Self, has a monkey-assistant, named Hanuman, who represents the mind (or intellect). In the story, at one point, Rama asks Hanuman, "How do you regard me?". And, Hanuman replies, "when I regard myself as the body, I am your servant; when I regard myself as the soul, I am part of you; but when I regard myself as the Universal Self, I am one with you."
The message from this anecdote is that your approach to spirituality or search for the Self or God, is entirely dependent on your attitude of who you identify yourself with. Or, who you believe yourself to be. If you identify yourself with the body and mind, then the Self is someone else. There is duality in this instance. More like the subject and object relationship in which you are the subject and Self or God is the object. In the story above, in the first two instances of how Hanuman relates himself to Rama, there is a distinct separation between himself and the object of his reverence, Rama. In the first two instances, Hanuman relates to Rama as either a servant or a part of Rama, but in the third instance, he SEES himself as no different from Rama (Self).
Depending on your attitude about who you think yourself to be determines how you approach spirituality. If you consider yourself to be a separate individual, separate from God or Self, then the path of Bhakti or devotion is what you actually end up pursuing. Although, you as a soul are not different from God or Self, you feel you are and hence you suffer. It is just an imagination that you are separate but yet you believe it to be true. In this instance, you long to be one with God or Self and you sing songs of praise of God or Self. You repeat the name of God or Mantra (or Japa) to avoid getting distracted from the thought of God. You meditate on God or Self in an effort to close the gap between your imagined identity as a separate self, and God. As an analogy, if a wave thinks itself to be separate from the Ocean, it prays to the Ocean to reveal itself for it longs to be one with the Ocean at some time. This is despite the fact that it has never been separate from the Ocean to begin with. Or like the rays of the Sun are no different from the Sun, and yet if the ray feels or thinks of itself as a distinct entity, it longs to be one with the Sun. In the same way you believe yourself to be a separate entity and in desperation pray, meditate, sing bhajans, do japa, in the hope that one day God will reveal Himself to you. At long last, the clouds of your self imposed ego clear, and the clear Light of the Self shines through in all its glory, and you exclaim in joy " I am the Self and I have never been anything but the Self".
On the other hand, you may be told by your Guru that you are none other than the Self, and because of your complete faith, trust and conviction in the teachings of the Guru you accept His words as such. Or else, you analyze and question the teachings of the Guru and reach the conclusion through direct experience of being the clear Awareness without attributes. You arrive at the conviction that the Guru is indeed correct in saying that you are the SELF and have never been anything but the SELF. This is the path of Jnana or Knowledge.
