Śrī Caitanya Caritamrta · Text Madhya 22.22
শ্রেয়ঃসৃতিং ভক্তিমুদস্য তে বিভো
ক্লিশ্যন্তি যে কেবলবোধলব্ধয়ে ।
তেষামসৌ ক্লেশল এব শিষ্যতে
নান্যদ্ যথা স্থূলতুষাবঘাতিনাম্ ॥ ২২ ॥
śreyaḥ-sṛtiṁ bhaktim udasya te vibho
kliśyanti ye kevala-bodha-labdhaye
teṣām asau kleśala eva śiṣyate
nānyad yathā sthūla-tuṣāvaghātinām
Translation
“ ‘My dear Lord, devotional service unto You is the only auspicious path. If one gives it up simply for speculative knowledge or the understanding that these living beings are spirit souls and the material world is false, he undergoes a great deal of trouble. He only gains troublesome and inauspicious activities. His endeavors are like beating a husk that is already devoid of rice. His labor becomes fruitless.’
