Answer
It is a matter of great joy that at such a young age, these matters are attracting your attention. This is evidence of growing introspection — in English it is called introspection. In Hindi, besides 'antar nirikshan' (inner observation), it is also called 'atma vishleshan' (self-analysis).
Spiritual self-analysis is the most powerful tool leading toward liberation. Keep using this tool.
A human being appears to be one "self" on the surface, but in reality there are multiple selves within. Here, "self" (atma) does not mean the Atman — the soul. Let us set aside the Atman for now — the Atman which is a fragment of the Lord and which is trapped within our gross body and subtle (linga) body. It is to reach that Atman that we are engaging in these discussions. For now, we are speaking of the "self" — what we are calling "atma" in Hindi.
So there are several types of selves within us. One is the self that, after performing its duty, also harbors expectations from others. Above that is another, higher self, which is observing the lower self as it performs duty while simultaneously nurturing expectations. This witnessing self is a higher self than the lower one.
In a person where this higher self begins to awaken, that person starts gradually bringing the layers of the lower self under control. When one becomes a completely impartial witness of the lower self, one begins to bring the lower self gradually under one's control.
This is the language of psychology. In the language of the Gita, this would be expressed as follows: Beyond the senses is the mind; beyond the mind is the intellect (buddhi); beyond the intellect is the Atman. Know and understand the Atman through the intellect, and having understood the Atman, control the mind through the intellect. And through the intellect, slay the enemy called desire. The "expectation" you feel from others is itself a form of desire! Therefore, the "self" that is observing that another self is harboring "expectations" — that observing self is what the Gita calls "buddhi." The self that is nurturing expectations is what the Gita calls "mana" (the mind).
If you continue to strengthen this higher self in the same way, you will gradually transcend the mind, and you will attain "atma-vijaya" (victory over the self), because then you will subdue prakriti (material nature) and begin to enter into the divinity of the Atman. Keep going.
I shall post the relevant verses from the Gita in this group shortly. You may already have them memorized. Simply continue to contemplate them and keep progressing on your spiritual journey. Hari Sharanam.
Saumya, I am now posting the Gita verses I had mentioned in my earlier post today.
All of us, without exception, primarily act driven by our prakriti — our nature. We remain helpless before our nature. But how to escape the trap of one's own nature — this wisdom is contained in these two verses. Bear in mind that prakriti has itself provided the ladder to escape its own enclosure. And that ladder is buddhi (the intellect). Buddhi is, technically, itself a component of prakriti, yet it is also the ladder out of prakriti. It is that very self which helps control the lower self (the mind). This is the ladder to moksha. What the Lord has called "buddhi" is not mere intelligence — it is refined intelligence, which would more aptly be called "buddhi-viveka" (discerning intellect).
'Indriyani paranyahurindriyebhyah param manah | Manasastu para buddhiryobuddheh paratastu sah' (3:42).
Meaning: The senses are said to be superior to the gross body. Superior to the senses is the mind. Superior to the mind is the intellect. And that which is superior to the intellect is the Atman (the Self).
'Evam buddheh param buddhva samstabhyatmanam atmana | Jahi shatrum mahabaho kamarupam durasadam' (3:43).
Meaning: Thus knowing the pure Atman to be superior to the intellect, steadying the self (the mind) by means of the self (the intellect), O mighty-armed one, slay this formidable enemy in the form of desire.
