"If one had to travel to a distant place for a few days, some requisites would be necessary. In this instance, the traveller is conversant about the place and period of stay. Yet without the prescribed requisites, travel is impossible. But when this body is abandoned and you have to proceed to an unknown path for an indefinite period of time, then how many requisites would be necessary? No material objects will be required then. The destination and duration of stay is unknown. That requisite has to be acquired in this present life through yogasadhana [spiritual practices] and carried over and that sadhana-derived experience will be the only requisite in the form of reformation. This requisite is imperishable."
