The video says MORE than four people means sangha. That is, a gathering of five or more ordained people is a sangha according to the Vinaya. I wanted to double check because Lama Phurbu Tashi asked me to edit an essay on refuge and he said five.
Having obtained the supreme freedoms
and conjunctions of the precious human existence,
endowed with faith, energy, and intelligence,
Having attended on a worthy spiritual friend
and received the pith of the holy instructions,
May we practice these properly, just as we have received them,
without obstacle or interruption.
In all our lives, may we practice and enjoy the holy dharma.
