Read all the books–or fall down

Srila Prabhupada: “read all the books–or fall down”

Madhya 25.278 : PURPORT : All the devotees connected with this Kṛṣṇa consciousness movement must read all the books that have been translated (Caitanya-caritāmṛta, Śrīmad-Bhāgavatam, Bhagavad-gītā and others); otherwise, after some time, they will simply eat, sleep and fall down from their position. Thus they will miss the opportunity to attain an eternal, blissful life of transcendental pleasure.

Without worshiping the arca-vigraha, the form or Deity of the Lord, one cannot understand such literature as Bhagavad-gita and Srimad-Bhagavatam.

So the temple worship is essential. So those who are against temple worship, Deity worship, they are not very intelligent class of men, foolish, mudha. (NoD 35 Neutral Love of God 175614/530501)
