How to achieve a steady mind?

60. Arjuna, the agitating senses are powerful enough to forcibly draw away the mind of a wise man even when he is striving hard keep away from them

61. To achieve a steady mind, he should restrain (from the agitating senses), contemplate (the ultimate objective) and take refuge in it. Steady mind is achieved when senses are under control.

62. When you contemplate on the objects of sense, attachment begins. From attachment springs desire, desire matures into passion and it assumes the form of anger

63. Anger leads to loss of understanding (confusion in the mind) and confused mind leads to forgetting the real objective, losing the memory of real objective leads to loss of wisdom. Owing to this loss of wisdom, the man is utterly ruined

64. Using the senses pertaining to the inner self, which has aversion and attachment in control and appreciating the situation in hand, leads to clarity and peace of mind

65. Peaceful and clear mind annihilates all the miseries of a person. Because the right knowledge reaches the person who has the clarity of mind, strengths it and makes it steady

66. The person who is unable to control his mind, cannot be self-restrained and in turn is unable to contemplate on the real objective that leads to peace of mind.

Bhagavad Gita - Chapter 2

54. Arjuna asked, “Krishna, what are indications of a person whose mind is firm and steady towards an objective? How does he speak? How does he rest? How does he act?”

55. When one casts off all the desires of his heart and is pleased with oneself, that person is said to be of a steady mind.

56. The one who is calm in calamity, who does not crave for pleasure and freed from fear, anger and attachment is said to be a sage with steady mind

57. The man with a steady mind is strong in his objective. But without affection towards it. He does not experience happiness when good things happen to him and does not experience aversion when bad things happen.

58. Akin to a tortoise that can instantaneously withdraw its limbs from all the sides, the man with the ability to withdraw his emotions from his objective will be able to hold to his steady mind

59. An abstinent person who can hold his senses and emotions, does not have worldly experiences (vile and guile). Only passion left within him is for the ultimate knowledge. After achieving that all his desires perish
