Did Baba suggest different types of meditation for people of varying capabilities? What were they?

Yes, Baba did suggest different approaches to meditation to suit different devotees. As recorded in Chapter 19, he first recommends meditating on his formless nature, which he identifies as pure knowledge, consciousness, or a cloud of bliss. However, acknowledging that this can be difficult, he offers an alternative. He advises that if meditating on the formless is not possible, one should instead meditate on his form with attributes (Saguna). This involves bringing his complete physical form, from head to toe, into the mind's eye day and night. Baba explains that this practice also leads to a one-pointed mind, which is the key to dissolving the sense of self and attaining the ultimate goal of meditation.
