One swan, the Self, is in the midst of this world; he is the very fire that has entered into the water. Only by knowing him does one pass beyond death; there is no other path to go by.
एको हंसः भुवनस्यास्य मध्ये स एवाग्निः सलिले संनिविष्टः । तमेव विदित्वा अतिमृत्युमेति नान्यः पन्था विद्यतेऽयनाय ॥ १५॥
