Yoga means to control the senses. And above the sense, the mind. So if you control the mind, the senses are controlled automatically. Your tongue wants to eat something nonsense, but if your mind is strong, mind says, "No. You cannot eat. You cannot eat anything except kṛṣṇa-prasāda." Then tongue is controlled. So senses are controlled by the mind. Indriyāṇi parāṇy āhur indriyebhyaḥ paraṁ manaḥ (BG 3.42). My body means senses, my activities means sensual activities, that's all. But above the senses is the mind. Above the mind is the intelligence. And above the intelligence is the spirit soul. If one is on the spiritual platform, on the soul platform, then his intelligence is spiritualized, his mind is spiritualized, his senses are spiritualized, he is spiritualized. This is the process of Kṛṣṇa consciousness. Because actually the spirit soul is working but he has given his power of attorney to this nonsense mind. He is sleeping. But when he's awakened, the master is awakened, the servant cannot do anything nonsense. Similarly if you are awakened in Kṛṣṇa consciousness, your intelligence, your mind, or your senses cannot act nonsensically. They must according to that. That is spiritualization. That is called purification.
In his material, conditional existence, the living entity gives power of attorney to his mind
SB Canto 4
The eleventh attendant, who is the commander of the others, is known as the mind. He is the leader of the senses both in the acquisition of knowledge and in the performance of work. The Pañcāla kingdom is that atmosphere in which the five sense objects are enjoyed. Within that Pañcāla kingdom is the city of the body, which has nine gates.
The mind is the center of all activities and is described here as bṛhad-bala, very powerful. To get out of the clutches of māyā, material existence, one has to control his mind. According to training, the mind is the friend and the enemy of the living entity. If one gets a good manager, his estate is very nicely managed, but if the manager is a thief, his estate is spoiled. Similarly, in his material, conditional existence, the living entity gives power of attorney to his mind. As such, he is liable to be misdirected by his mind into enjoying sense objects. Śrīla Ambarīṣa Mahārāja therefore first engaged his mind upon the lotus feet of the Lord. Sa vai manaḥ kṛṣṇa-padāravindayoḥ (SB 9.4.18). When the mind is engaged in meditation on the lotus feet of the Lord, the senses are controlled. This system of control is called yama, and this means "subduing the senses." One who can subdue the senses is called a gosvāmī, but one who cannot control the mind is called go-dāsa. The mind directs the activities of the senses, which are expressed through different outlets, as described in the next verse.
Bhagavad-gita As It Is Lectures
Pradyumna: "By assimilating the instructions of the Bhagavad-gītā one is sure to become released from such bewilderment."
Prabhupāda: Yes. Therefore you have to understand Bhagavad-gītā is left for you. Kṛṣṇa has left before going away from this planet. He gave the instruction: "This is the position. You are like this. Your position is like this. You are now in trouble. You are in material existence. Why you are struggling for existence simply making your mind as the guide?" Manaḥ ṣaṣṭhāni indriyāṇi prakṛti-sthāni karṣati. Kṛṣṇa says in the Bhagavad-gītā that "These living entities, they are My part and parcel. They're as good as I am, but..." Manaḥ ṣaṣṭhāni indriyāṇi prakṛti-sthāni karṣa... "They have made the mind, given the power of attorney to the mind, and therefore they are forced to the struggle for existence." This is the statement of Bhagavad-gītā.
Prabhupāda: (recites verse)
- pañcabhiḥ kurute svārthān
- pañca vedātha pañcabhiḥ
- ekas tu ṣoḍaśena trīn
- svayaṁ saptadaśo 'śnute
- (SB 6.1.50)
So we are fallen into great ocean of nescience, covered. First of all the five senses, knowledge-acquiring senses, jñānendriya and karmendriya, working senses, ten, and sense object... We have got eyes; therefore eyes are engaged for seeing something beautiful, rūpa. Rasa. Rasa means taste. That is the business of the tongue. And to see beautiful thing, that is the business of the eyes. Rūpa, rasa, śabda. Śabda means sound. The ear, we have got ear. We want to hear nice songs, music, radio, television. So ear is there; the objects are there. Rūpa, rasa, śabda, gandha, smelling. There is good odor also, bad odor also. Rūpa, rasa, gandha, śabda, sparśā. In this way we are entangled, completely under the laws of material nature. I am the spirit soul. Saptadaśaḥ. I have given my power of attorney to the mind, and mind is creating different varieties of the śabda, sparśā, rūpa, rasa, gandha, śabda, sparśā. In this way, life after life, as it is explained in the previous verse,
- yathājñas tamasā
- upāste vyaktam eva hi
- na veda pūrvam aparaṁ
- naṣṭa-janma-smṛtis tathā
