Bhagavad-gita As it is

BG Chapters 13 - 18

Beginning from practicing humility up to the point of realization of the Supreme Truth, the Absolute Personality of Godhead, this process is just like a staircase beginning from the ground floor up to the top floor. Now on this staircase there are so many people who have reached the first floor, the second or third floor, etc., but unless one reaches the top floor, which is the understanding of Kṛṣṇa, he is at a lower stage of knowledge.

BG 13.8 (1972), Translation and Purport

Humility, pridelessness, nonviolence, tolerance, simplicity, approaching a bona fide spiritual master, cleanliness, steadiness and self-control; renunciation of the objects of sense gratification, absence of false ego, the perception of the evil of birth, death, old age and disease; nonattachment to children, wife, home and the rest, and evenmindedness amid pleasant and unpleasant events; constant and unalloyed devotion to Me, resorting to solitary places, detachment from the general mass of people; accepting the importance of self-realization, and philosophical search for the Absolute Truth-all these I thus declare to be knowledge, and what is contrary to these is ignorance.

As far as self-realization is concerned, it is clearly stated here that bhakti-yoga is especially practical. As soon as there is a question of devotion, one must consider the relationship between the Supersoul and the individual soul. The individual soul and the Supersoul cannot be one, at least not in the bhakti conception, the devotional conception of life. This service of the individual soul to the Supreme Soul is eternal, nityam, as is clearly stated. So bhakti or devotional service is eternal. One should be established in that philosophical conviction, otherwise it is only a waste of time, ignorance.

In the Śrīmad-Bhāgavatam, this is explained; vadanti tat tattva-vidas tattvaṁ yaj jñānam advayam. "Those who are actually knowers of the Absolute Truth know that the Self is realized in three different phases as Brahman, Paramātmā and Bhagavān." (SB 1.2.11) Bhagavān is the last word in the realization of the Absolute Truth; therefore one should reach up to that platform of understanding the Supreme Personality of Godhead and thus engage in the devotional service of the Lord. That is perfection of knowledge.

Beginning from practicing humility up to the point of realization of the Supreme Truth, the Absolute Personality of Godhead, this process is just like a staircase beginning from the ground floor up to the top floor. Now on this staircase there are so many people who have reached the first floor, the second or third floor, etc., but unless one reaches the top floor, which is the understanding of Kṛṣṇa, he is at a lower stage of knowledge. If anyone wants to compete with God and at the same time make advancement in spiritual knowledge, he will be frustrated. It is clearly stated that without humility understanding is harmful. To think oneself God is most puffed up. Although the living entity is always being kicked by the stringent laws of material nature, still he thinks, "I am God" because of ignorance. One should be humble and know that he is subordinate to the Supreme Lord. Due to rebellion against the Supreme Lord, one becomes subordinate to material nature. One must know and be convinced of this truth.
