What is the purpose of spiritual sadhana ?
The fruit comes from the tree. But can the tree know the nature of the fruit? When two sticks are rubbed against each other, fire emerges. But do the sticks know that fire is latent in them? Likewise, the Divine is latent in man. It is through the process of enquiry and sadhana that man can discover the Divine in him. It is like churning buttermilk to get the butter in it. Through sadhana and pure love (Bhakti) man can manifest his divinity. (SSS Vol 19, pg 126)
