Nope. The 4 Drakpas are :-
1) Losang Drakpa
2) Dulzin Drakpa Gyeltsen
3) Panchen Sonam Drakpa
4) Tulku Drakpa Gyeltsen
Je Tsongkhapa and Dulzin Drakpa Gyeltsen manifested as Lama and disciple but both are in reality Manjushri! This ability lies in the hands of a fully enlightened Being and hence, the 4 Drakpas' incarnation is an extremely high incarnation wherever he may be at this moment.
Yes. Big Uncle is right. The above 4 Drakpas mentioned above is in fact the previous incarnations of DS which have the same mindstream with Manjushri. Therefore, we can have full confidence in DS as he is the wisdom Buddha manifested in the form of a worldly protector so that he can come to our aid quicker based on our karma at this time of kaliyuga (degenerate age).
Also, if we look at the accomplishments of Losang Drakpa (Tsongkapa), Dulzin Drakpa Gyeltsen, Panchen Sonam Drakpa and Tulku Drakpa Gyeltsen and their past deeds, we should have no doubt that DS who have the same mindstream with these being is capable of all the deeds for these beings and is definitely a qualified Dharma Protector that we can fully rely on. How fortunate we are to have the merits to meet with such a protector!
