How to understand Hanuman showing Lord Rama along with Siitaa and Lakshmana in His heart instead of human incarnation alone?

[Shri Ganesh V asked: Pādanamaskāram Swamiji, I always understood that a devotee should have only the contemporary human incarnation in his mind and heart but in Hanuman Chaaliisaa, it is written that Lord Hanuman had Lord Rama along with Devi Siitaa and Lakshmana in His heart. Devi mam told me that He considered Himself to be the servant of servant, in this way ego doesn't creep inside in His mind. I have accepted this point but is there something more in that verse? At Your divine feet, Ganesh V]

Swami Replied: - A true devotee is always kept on head by God. God is pleased more if one serves the devotee than serving Himself!
