What is the path to experiencing oneness with Sai Baba as described in the Sai Satcharitra?

According to Chapter 44, the path to experiencing oneness with Sai Baba involves a dedicated internal practice. Baba states, "While practicing this, my omnipresence will be experienced. Then you, having attained harmony with me, will enjoy complete oneness." This practice involves focusing on the "consciousness-form," which leads to the purification of the inner heart. This inner cleansing is described as a spiritual "bath in the Ganges for you, without touching the water of the Ganges." By establishing oneself in one's own true nature and avoiding the pride that binds, a devotee can achieve a state of constant awareness and harmony with Sai, rendering formal states like Samadhi unnecessary.
