In household life one is ordered to execute many yajñas and fruitive activities, especially the vivāha-yajña [the marriage ceremony for sons and daughters] and the sacred thread ceremony. These are all the duties of a gṛhastha, and they are very extensive and troublesome to execute. They are compared to a big hill over which one must cross when one is attached to material activities. A person desiring to cross over these ritualistic ceremonies certainly feels pains like the piercing of thorns and pebbles endured by one attempting to climb a hill. Thus the conditioned soul suffers unlimitedly.
