Just worship Sri Gaurahari [Caitanya Mahaprabhu], who is always affectionate toward His devotees. He is the same Supreme Godhead, Krsna, who sported in the cowherd pastures of Vraja and stole the hearts of Nanda and Yasoda.

Srila Bhaktivinoda Thakura
Bhoga-arati, Verse 1 (From Gitavali)

All the Vedas describe the lotus feet of the Supreme Personality of Godhead.

Katha Upanisad 1.2.15

I, the Soul of all beings, am not as satisfied by ritual worship, brahminical initiation, penances, or self-discipline as I am by faithful service rendered to one's spiritual master.

Lord Sri Krsna
Srimad-Bhagavatam 10.80.34

All the Vedas declare, "Chant the holy name of Lord Krsna. By chanting you will attain spiritual love and bliss that has no end." Again they say, "The great liberated souls in the spiritual world always chant the holy name."

Srila Haridasa Thakura
Sri Hari-nama-cintamani 7.53-54

My dear friend, if you are indeed attached to your worldly friends, do not look at the smiling face of Lord Govinda [Krsna] as He stands on the bank of the Yamuna River at Keshi Ghat. Casting sidelong glances, He places His flute to His lips, which seem like newly blossomed twigs. His transcendental body, bending in three places, appears very bright in the moonlight.

Srila Rupa Gosvami
Bhakti-rasamrta-sindhu 1.2.239

A pure devotee, who is attached to the activities of devotional service and who always engages in the service of My lotus feet, never desires to become one with Me. Such a devotee, who is unflinchingly engaged, always glorifies My pastimes and activities.

Lord Kapila
Srimad-Bhagavatam 3.25.34

The Lord of Gokula [Krsna] is the transcendental Supreme Godhead, the own Self of eternal ecstasies. He is the superior of all superiors and is busily engaged in the enjoyments of the transcendental realm and has no association with His mundane potency.

Lord Brahma
Sri Brahma-samhita 5.6
