Srila Prabhupada
Jagat means moving. And Jagat-nātha, nātha means the proprietor—master, proprietor. So Jagannātha means the proprietor or the master of all these movements, He is Jagannātha. And Balabhadra, Balarāma, bala means strength, and rāma means enjoyment. So Balarāma means who gives you spiritual strength for enjoying eternal blissful life. He is Balarāma. And Subhadrā, su means auspicious, and bhadra means well-being. Subhadrā, Jagannātha and Balarāma combined together are present before you to reclaim you all from your miserable condition of life. That is the purport of this Ratha-yātrā Festival. If anyone sees on the cart Jagannātha, Subhadrā and Baladeva, then he does not take birth again in this material world. Ratheja vamanaṁ dṛṣṭa.

If you want actual happiness, then you have to undergo austerity, tapasya. Tapo divyaṁ putrakā yena śuddhyet yasmād brahma-saukhyam anantam. You are hankering after happiness. That happiness, brahma-sukha, eternal happiness, you will get by practicing tapasya. So don't believe, don't make friendship with your restless mind. This is the instruction. Don't make friendship. Simply beat the mind with shoes and broomstick, otherwise cannot bring in control. And other alternative is kevalayā bhaktyā. So if you can engage your mind at the lotus feet of Kṛṣṇa, then it is possible. Sa vai manaḥ kṛṣṇa-padāravindayoḥ ((SB 9.4.18). Then Kṛṣṇa will control. Kṛṣṇa means light. Darkness . . . you are suffering in the darkness. So somehow or other if you bring a light, there is no darkness.
kṛṣṇa-sūrya-sama; māyā haya andhakāra
yāhāṅ kṛṣṇa, tāhāṅ nāhi māyāra adhikāra
(CC Madhya 22.31)
If you keep always within your mind Kṛṣṇa, Kṛṣṇa's lotus feet . . . you can see Kṛṣṇa's lotus feet, Deity, Baladeva, Balarāma, how He is nicely standing. You can see the nice lotus feet. Don't try to see the face all of a sudden. Try, practice to see the lotus feet constantly. Sa vai manaḥ kṛṣṇa-padāra . . . this is a chance. This temple means to practice how to think of Kṛṣṇa's lotus feet, Balarāma's lotus feet, always. Man-manā bhava mad-bhaktaḥ (BG 18.65). Immediately you become bhakta. And as soon as you become a bhakta, kecit kevalayā bhaktyā vāsudeva-parāyaṇāḥ, dhunvanti aghaṁ kṛtsnam (SB 6.1.15): all kinds of disturbances will be subsided, dhunvanti.
