Text 14] The Manus, Administrators of the Universe
23
“Knowledge of self-realization, even though freed from all material affinity, does not look well if devoid of a conception of the Infallible [God].”  Jñānīs  recommend that one adopt  naiṣkarmya  by not doing anything but simply meditating and thinking of Brahman, but this is impossible unless one realizes Parabrahman, Kṛṣṇa. If there is no Kṛṣṇa consciousness, any kind of activity, be it philanthropic, political or social, simply causes  karma-bandhana , bondage to material work.
As long as one is entangled in  karma-bandhana , one must accept different types of bodies that spoil the human form of facility. Therefore, in  Bhagavad-gītā  (6.3)  karma-yoga  is recommended:
ārurukṣor muner yogaṁ 
                karma kāraṇam ucyate 
                yogārūḍhasya tasyaiva 
                śamaḥ kāraṇam ucyate
“For one who is a neophyte in the  yoga  system, work is said to be the means; and for one who has already attained to  yoga , cessation of all material activities is said to be the means.” Nonetheless:
karmendriyāṇi saṁyamya 
                ya āste manasā smaran 
                indriyārthān vimūḍhātmā 
                mithyācāraḥ sa ucyate
“One who restrains the senses and organs of action, but whose mind dwells on sense objects, certainly deludes himself and is called a pretender.” (Bg. 3.6) One should act for Kṛṣṇa very seriously in order to become fully Kṛṣṇa conscious and should not sit down to imitate such great personalities as Haridāsa Thākura. Śrila Bhaktisiddhānta Sarasvatī Thākura condemned such imitation. He said:
duṣṭa mana! tumi kisera vaiṣṇava? 
                pratiṣṭhāra tare,      nirjanera ghare, 
                tava hari-nāma kevala kaitava.
“My dear mind, what kind of devotee are you? Simply for cheap adoration, you sit in a solitary place and pretend to chant the Hare Kṛṣṇa
