The epistemology and etymology of the Gaudia Vaisnava tradition along with its spiritual and esoteric practices are central to Gaudia Vaisnavaism , whereas peripheral beliefs and practices about various aspects of  learning and approaches to the cor beliefs , utilising practical living  and  gradual methods of purification that are derived from the need to understand and progress towardand enter into the core beliefs ,  are more easily reflected upon and understood   by a majority . These  are easily accessible . ie. From proper understanding of ISKCON and its broad  approach in teaching  Vedic culture. 

.Such  PERIPHERAL practices are also at times adapted and  changed , according to time place and  circumstances. 

The two distinct  systems  of cor esoteric and peripheal beliefs and practices should give support to each other , but the PERIPHERAL practices and beliefs should not supersede the core beliefs  or take priority over the practices that bring one to the param gatim , the ultimate goal that Mahāprabhu clearly defines in his conversations with Ramananda Roy. 

As ISKCON spreads it’s wings it should probably make clear to itself , and its following,  what is its function in the above considerations . Some will argue  , that ISKCON should play a direct role in all the PERIPHERAL and esoteric core practices and others will stick strongly to the argument that only the core beliefs should be prioritised and its practices are its main concern , and that automatically if the core beliefs and practices are prioritised its mission will be successful and  if it loses sight of its deep core beliefs and practices, everything will be lost in time , they have a point of course.

In Bhagavad Gita 2.46.

Krishna speaks of this topic , all purposes of a small well can be served by a great ocean , all purposes of the Vedas are served by one who knows the purposes behind the Vedas .
