The Relationship of Dharma and Sadhana

What is the relationship of Dharma, the universal way, to Sadhana, a spiritual way?

Dharma is THE way. Use of this term implies that dharma exists whereas sadhana is an individual's spiritual way that can be realized. Use of the term sadhana implies that an individual can access the dharma, and, in their own unique way. While dharma encompasses all the different sadhanas, dharma IS also all of them.

A hypernym is a broader term than its more specific counterpart. For example, tree is the hypernym of oak and purple is a hypernym of violet. 

So, I guess dharma is a hypernym of sadhana.
