I'm struggling with a lack of purpose after my studies. Did Baba ever teach complex philosophical concepts that could help me find meaning, or was it just simple stories?

According to the texts from Chapter 0, Maharaj did not openly explain profound Vedanta subjects or give formal discourses on the Upanishads. His advice was primarily based on general ethical principles. The source explains that the Sadguru's practice is to first purify the disciple's ground and then sow the seed of knowledge. However, Chapter 0 also notes that the advice received from Maharaj in the form of direct experience was considered infinitely more valuable than his verbal advice, leading to the highest benefit for devotees who approached him with faith.
