BG 2.66

One who is not connected with the Supreme [in Kṛṣṇa consciousness] can have neither transcendental intelligence nor a steady mind, without which there is no possibility of peace. And how can there be any happiness without peace?

2.66. The capacity to decide is not for one who is not a master of Yoga; and concentration of mind is not for one who is not a master of Yoga; and peace is not for one who does not concentrate; wherefrom could happiness come to one who has no peace ?

2.66 Right discrimination is not for him who cannot concentrate. Without concentration, there cannot be meditation; he who cannot meditate must not expect peace; and without peace, how can anyone expect happiness?

2.66 See Comment under 2.68

2.66 In him who does not focus his mind on Me but is engaged only in the control of senses by his own exertion, the Buddhi or the right disposition that is concerned with the pure self never arises. Therefore he fails in the practice of meditation on the self. In one who cannot think of the pure self, there arises the desire for sense objects; in him serenity does not arise. How can eternal and unsurpassed bliss be generated in him who is not serene but is attached to sense-objects? [The idea is that without the aid of devotion to God, the effort to control the senses by one's will power alone will end in failure.] Sri Krsna speaks again of the calamity that befalls one who does not practise the control of the senses in the way prescribed above:

2.66 Ayuktasya, for the unsteady, for one who does not have a concentrated mind; na asti, there is no, i.e. there does not arise; buddhih, wisdom, with regard to the nature of the Self; ca, and; there is no bhavana, meditation, earnest longing [Longing to have a continuous remembrance of the knowledge of Brahman which arises in the mind from hearing the great Upanisadic sayings (maha-vakyas).] for the knowledge of the Self; ayuktasya, for an unsteady man. And similarly, abhavayatah, for an unmeditative man, who does not ardently desire the knowledge of the Self; there is no santih, peace, restraint of the senses. Kutah, how can there be; sukham, happiness; asantasya, for one without peace? That indeed is happiness which consists in the freedom of the senses from the thirst for enjoyment of objects; not the thirst for objects that is misery to be sure. The implication is that, so long as thirst persists, there is no possibility of even an iota of happiness! It is being stated why a man without concentration does not possess wisdom:

2.66 There is no Buddhi for the unintegrated, nor for him is there contemplation of the self, and for him without contemplation of the self, there is no peace; and for one lacking peace, where is happiness?

2.66 For the unsteady there is no wisdom, and there is no meditation for the unsteady man. And for an unmeditative man there is no peace. How can there be happiness for one without peace?
