The Vedas, Hari Bhakti Vilas and Vaisnava etiquette are full of them. But in the Vaisnava life we see also that rules and laws are to be broken again and again by the overpowering influence of the Vaisnava love and generosity. There are innumerable examples to proof this point. The voluntary nature of Vaisnava missions, what to speak of such a body as the Visva Vaisnava Raj Sabha or the Sarasvat Gaudiya Sammelan, do not drive on rules, but only on Sadhu Sanga, nama kirtan and Love. Love for Krishna and love for the fellow Vaisnavas, be they senior or junior in their advancement.
Love also means trust.
In a loving relationship rules are disturbing rather then promoting an increase of that love. Rules regarding Gurus, disciples, initiations, Sannyas, reinitiations, Sadhana or Sadacara belong into the scriptures to be explained and applied by Bhagavata personalities. If non realized persons or committees want to explain such rules, they most likely will kill the inner meaning of them, which is to make everyone happy in the family of Krishna Consciousness. Those who try to dominate other Vaisnavas through rules will very quickly find themselves surrounded by those who care only for external benefits and not for the Vaisnava substance. Sannyasis and initiation were given and are still given under very surprising circumstances in almost all Vaisnava missions, and not always the result is a success.
