Bhagavad-gita As it is

BG Chapters 13 - 18

Simplicity means that without diplomacy one should be so straightforward that he can disclose the real truth even to an enemy. As for acceptance of the spiritual master, that is essential, because without the instruction of a bona fide spiritual master, one cannot progress in the spiritual science.

BG 13.8-12 (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.

Tolerance means that one should be practiced to bear insult and dishonor from others. If one is engaged in the advancement of spiritual knowledge, there will be so many insults and much dishonor from others. This is expected because material nature is so constituted. Even a boy like Prahlāda, who, only five years old, was engaged in the cultivation of spiritual knowledge, was endangered when his father became antagonistic to his devotion. The father tried to kill him in so many ways, but Prahlada tolerated him. So, for making advancement in spiritual knowledge, there may be many impediments, but we should be tolerant and continue our progress with determination.

Simplicity means that without diplomacy one should be so straightforward that he can disclose the real truth even to an enemy. As for acceptance of the spiritual master, that is essential, because without the instruction of a bona fide spiritual master, one cannot progress in the spiritual science. One should approach the spiritual master with all humility and offer him all services so that he will be pleased to bestow his blessings upon the disciple. Because a bona fide spiritual master is a representative of Kṛṣṇa, if he bestows any blessings upon his disciple, that will make the disciple immediately advanced without the disciple's following the regulated principles. Or, the regulated principles will be easier for one who has served the spiritual master without reservation.

Cleanliness is essential for making advancement in spiritual life. There are two kinds of cleanliness: external and internal. External cleanliness means taking a bath, but for internal cleanliness, one has to think of Kṛṣṇa always and chant Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/Hare Rāma. Hare Rāma, Rāma Rāma Hare Hare. This process cleans the accumulated dust of past karma from the mind.
