Acharya Prashant explains that the Guru and the disciple are, in reality, internal entities within you. These internal entities then appear externally in various gross forms. Your mind, which is somewhat naive and doesn't understand certain things, is called the disciple or 'chela'. The mind is eager to learn. That which the mind wants to approach for learning is called the Guru. The Self (Atman) is the Guru. The peace of the mind is called the Atman. The mind is restless and wants peace; it needs the Atman. Another name for the Atman is Guru. From the perspective of the mind, you will say, 'I am restless, I need to find a Guru.' If you understand from the perspective of the Self, you will see that it is the blessing of the Self that the mind is feeling the restlessness to find it. You can look at it in any way you want. You can say that the mind is thirsty for peace, or you can say that peace pulls the mind. The difference between these two sentences is only about which entity you see as the doer. When you say the mind is restless for peace, you have made the mind the doer. When you say peace is calling the mind, you have made peace the doer. In reality, these two are not separate. Ultimately, only one of them is true, which is peace. There are not two truths. So, to speak with absolute truth, you would have to say, 'Who is going to whom? Who is calling whom? There are not two.' However, since you have to speak, if you look from the mind's perspective, you will have to say that the mind seeks peace, the disciple seeks the Guru. And if you look from the Guru's perspective, you will say that on the surface it seems the disciple is searching for the Guru, but the inner truth is that the Guru is sitting inside the disciple and, from within, tells the disciple to search for the Guru outside. The Guru that sits inside is formless and attributeless (nirgun, nirakar). This formless Guru is not visible to the disciple with form. The disciple is with form and attributes (sagun, sakar). The real Guru, though sitting inside the disciple, is not visible to the disciple because the disciple is unaware of its presence. So, the Guru helps the disciple by becoming manifest with form for the disciple's sake. Then, you see someone in front of you whom you call 'Guruji'. That 'Guruji' can be anything—a book, a person, a situation. That which is outside is actually an expression of the one within. Every disciple needs a Guru, whether it is a formless Guru or a Guru with form.
