Avatarika
तत्र अस्य इदं शरीरं परित्यज्य गच्छतः न अन्यस्य देहा-न्तरस्योपादाने सामर्थ्यमस्ति, देहेन्द्रियवियोगात्; न चअन्ये अस्य भृत्यस्थानीयाः, गृहभिव राज्ञे, शरीरान्तरं कृत्वाप्रतीक्षमाणा विद्यन्ते; अथैवं सति, कथम् अस्य शरीरान्त-रोपादानमिति ।उच्यते- सर्वं ह्यस्य जगत् स्वकर्मफलो-पभोगसाधनत्वाय उपात्तम्; स्वकर्मफलोपभोगाय च अयंप्रवृत्तः देहाद्देहान्तरं प्रतिपित्सुः; तस्मात् सर्वमेव जगत्स्वकर्मणा प्रयुक्तं तत्कर्मफलोपभोगयोग्यं साधनं कृत्वा प्रती-क्षत एव, ‘कृतं लोकं पुरुषोऽभिजायते’ इति श्रुतेः- यथास्वप्नात् जागरितं प्रतिपित्सोः ।तत्कथमिति लोकप्रसिद्धोदृष्टान्त उच्यते-
In plain words
Once this self lets go of the body and moves on, no one else can build a new body for it — there is no thread left connecting them, no shared sense or nerve. And it is not as if a household of servants somewhere has already finished building a new house and stands waiting for their king to arrive. So how does a new body get ready in time? Here is the answer: the whole world has already been claimed, quietly, by your own past actions, set aside for exactly the experience those actions are due to yield. You, driven by your own doing, are already on your way from one body toward another; and because of that, the world your past actions assembled is standing by, fitted precisely to what you are owed — the scripture says it directly: a person is born into the very world he made. It is no different from falling asleep already carrying, somehow, exactly what your dream will need. How that actually works is what the next illustration shows.

There, for this one who abandons this body and departs, no other has the capacity to take up another body for him, since [that other] is disconnected from his body and organs; nor are there others belonging to him, like servants, who, having made ready another body in advance, wait for him the way [servants prepare] a house for a king. If this is so, how does he take up another body? It is said: the entire world has been laid hold of by him for the purpose of being an instrument for the experience of the fruit of his own action; and, set upon experiencing the fruit of his own action, this one proceeds, desiring to go from body to another body; therefore the entire world, set to work by his own action, having made ready an instrument fit for the experience of that action's fruit, waits, precisely — according to the scriptural text, 'a person is born into the world he has made' — just as it waits for one desiring to pass from dream into the waking state. As to how that is, a well-known worldly illustration is now stated —
