When an avatar is born as a human being, he behaves like a human being. A great soul like Rakhal — who was an ishwarakoti (a godlike soul), nityasiddha (an ever-perfect soul), and a companion of Krishna — had a little boyish jealousy. “It was quite unbearable for him,” said Sri Ramakrishna, “if I loved anyone but him. He would feel wounded at heart. At that I felt greatly concerned lest he should harm himself by being jealous of those whom Mother would bring here.”
In August 1884 Rakhal became sick and was sent to Calcutta for treatment. Later he went to Vrindaban with Balaram for a change. Just prior to that the Master saw in a vision that the Mother was removing Rakhal from Dakshineswar. He eagerly prayed for his spiritual son: “Mother, he [Rakhal] is a mere boy, quite ignorant; that is why he sometimes feels piqued. If, for the sake of your work, you remove him from here for some time, keep him in a good place and in a blissful mood.”
In Vrindaban Rakhal again became sick, which greatly concerned the Master. He knew that Rakhal’s past life was connected with Krishna in Vrindaban; if he were to remember that, he might give up the body. The Master prayed to the Mother and She comforted him. Gradually Rakhal got well and stayed there nearly four months.
After returning from Vrindaban, Rakhal went to his home in Calcutta. He visited the Master at Dakshineswar and met the new young disciples. He realized then that his guru belonged to all as the moon shines equally upon all; and his jealousy left him forever by the grace of his guru. (Source: God Lived with Them)
