BG 13.8-12

Humbleness; freedom from hypocrisy; non-violence; forgiveness; simplicity; service of the Guru; cleanliness of body and mind; steadfastness; and self-control; dispassion toward the objects of the senses; absence of egotism; keeping in mind the evils of birth, disease, old age, and death; non-attachment; absence of clinging to spouse, children, home, and so on; even-mindedness amidst desired and undesired events in life; constant and exclusive devotion toward Me; an inclination for solitary places and an aversion for mundane society; constancy in spiritual knowledge; and philosophical pursuit of the Absolute Truth—all these I declare to be knowledge, and what is contrary to it, I call ignorance.

BG 18.51-53

One becomes fit to attain Brahman when he or she possesses a purified intellect and firmly restrains the senses, abandoning sound and other objects of the senses, casting aside attraction and aversion. Such a person relishes solitude, eats lightly, controls body, mind, and speech, is ever engaged in meditation, and practices dispassion. Free from egotism, violence, arrogance, desire, possessiveness of property, and selfishness, such a person, situated in tranquility, is fit for union with Brahman (i.e., realization of the Absolute Truth as Brahman).
