Acharya Prashant explains that Shri Krishna acts out of a deep commitment to righteousness rather than personal gain, viewing him as a person who refuses to let unrighteousness prevail. Regarding the necessity of a spiritual teacher, he addresses the contradiction in using Mahatma Buddha's teaching to "be your own light" as an argument against having a teacher. He notes that since following one's own mind has resulted in suffering, external guidance is initially essential. He emphasizes that the instruction to be one's own light is actually a parting message intended for a student who has completed their training and is ready to be independent. He warns that misinterpreting this final stage as a starting point allows the ego to avoid the discipline and transformation provided by a teacher. A genuine teacher's role is to eventually make themselves unnecessary by lighting the student's inner lamp. Furthermore, he references Patanjali's Yoga Sutras to show that while systematic steps exist, the ultimate goal of realization is paramount and can sometimes occur spontaneously. He concludes that spiritual milestones like detachment and renunciation do not always follow a rigid sequence, as the path is unique for everyone.
