I struggle with abstract meditation. What practical advice does Baba offer for someone who finds it difficult to meditate on a formless concept like 'pure consciousness'?

Sai Baba provides very practical advice for this exact situation in Chapter 19. He acknowledges that meditating on the formless aspect of pure knowledge and consciousness may not be possible for everyone. Therefore, he offers an alternative path: meditating on his form with attributes (Saguna). He specifically instructs one to 'bring me into your mind from head to toe, day and night.' This practice of consistent, focused visualization on his physical form helps the mind become one-pointed. Over time, this method will also lead to the dissolution of the self, meditation, and object of meditation, allowing you to attain the same state of pure consciousness.
