नास्ति बुद्धिरयुक्तस्य न चायुक्तस्य भावना । न चाभावयतः शान्तिरशान्तस्य कुतः सुखम् ॥६६॥
nāsti buddhir ayuktasya na cāyuktasya bhāvanā na cābhāvayataḥ śāntir aśāntasya kutaḥ sukham
na asti — there cannot be; buddhiḥ — transcendental intelligence; ayuktasya — of one who is not connected (with Kṛṣṇa consciousness); na — not; ca — and; ayuktasya — of one devoid of Kṛṣṇa consciousness; bhāvanā — fixed mind (in happiness); na — not; ca — and; abhāvayataḥ — of one who is not fixed; śāntiḥ — peace; aśāntasya — of the unpeaceful; kutaḥ — where is; sukham — happiness.
But an undisciplined person, who has not controlled the mind and senses, can neither have a resolute intellect nor steady contemplation on God. For one who never unites the mind with God there is no peace; and how can one who lacks peace be happy?
Unless one is in Kṛṣṇa consciousness, there is no possibility of peace. So it is confirmed in the Fifth Chapter (5.29) that when one understands that Kṛṣṇa is the only enjoyer of all the good results of sacrifice and penance, that He is the proprietor of all universal manifestations, and that He is the real friend of all living entities, then only can one have real peace. Therefore, if one is not in Kṛṣṇa consciousness, there cannot be a final goal for the mind. Disturbance is due to want of an ultimate goal, and when one is certain that Kṛṣṇa is the enjoyer, proprietor and friend of everyone and everything, then one can, with a steady mind, bring about peace. Therefore, one who is engaged without a relationship with Kṛṣṇa is certainly always in distress and is without peace, however much he may make a show of peace and spiritual advancement in life. Kṛṣṇa consciousness is a self-manifested peaceful condition which can be achieved only in relationship with Kṛṣṇa.
