Social systems of the Vedas have form & spirit . The form is important, but the essence is the spirit. Thus, from four social classes, and its social systems one progresses to the social and spiritually progressive psth of karma yoga, leading to extensive knowledge through jnana yoga , leading to working exclusively for Krishna in niskarma yoga , leading to  deep remembrances of Krishna,  akin to astanga yoga ,  then the process of aquiring through the different depths of meditations as given by the Goswamis of Vrndavana bhakti yoga in practice  , ie sadhana  practice & bhakti yoga in ragganuga practice ,cultivating remembrances in spontaneous devotion in love .

Ragganuga bhakti is again given trancendental   categorization in  spontaneous ontological calculations of love,  based on loving  service in more neutral positions to parenthood to friendship to relationship in conjugal  love , and further categories are described in conjugal love , technically called Svakiya and Parakiya

As a comparson  , one ultimately finds in the  loving relationships of young lovers all the qualities of the other types of relationships, ie friendship,  a service attitude and also a caring motherly effection ,but the confidentiality of the lovers can not be brought into any of the other types of relationships.

The Vedas culminate in an indepth exposition of the highest and most intimate of relationships that is possible with Divinity,  it looks externally something like relationships found in this world,  but really there is no comparison to the ever new , ever fresh exchanges of spiritual love with an eternal spiritual body and  with unlimited spiritual senses , that is ever new and ever increasing in quality.

Comparison between cut broken cheap glass and the best of the diamonds can never be made , but perhaps by a fool ,who has no culture ,education, or intelligence may equate it , or think his broken glass to be a diamond.
