Seeking comes from within
When we understand that every being is a unique creation of the Universe, that the same divinity that is in us is in them also, we automatically radiate humility and the absence of pride. All these qualities that are supposed to be radiated by a seeker should simply happen from within. This is what Kṛṣṇa explains.
Another important thing: How should we approach an Enlightened spiritual Master or ācāryopāsana? He talks about this in another verse also—tad viddhi praṇipātena paripraśnena sevayā (4.34). It means that we should approach the Master with questions and request him to answer the questions.
Especially in Vedānta, the Vedic system, the Master plays a major role. Why? Unless we see someone continuously living in the consciousness and continuously expressing that consciousness, our unconscious refuses to believe it is possible.
When we see a living Enlightened Master, our emotions also automatically start experiencing it. Our unconscious, which continuously questions, becomes silent when we see a living Master. With books we learn through verbal language; with a Master we learn through his body language. He is a living example that proves the truth can become a reality for us in our life.
