There are many sages who are expert in performing austerities; there are many men who give much in charity; there are many famous men, scholars and thinkers, and there are those who are very expert in reciting Vedic hymns. Although these are all auspicious, unless one utilizes his resources and performs his activities to attain devotional service to the Lord, he cannot attain the desired results. Therefore in Śrīmad-Bhāgavatam (SB 2.4.17) Śukadeva Gosvāmī offered his respectful obeisances unto the Supreme Lord as the only person who can award success.
It is accepted by all types of philosophers and transcendentalists that one who lacks knowledge cannot be liberated from material entanglement. Yet knowledge without devotional service cannot possibly award liberation. In other words, when jñāna, or the cultivation of knowledge, opens onto the path of devotional service, it can give one liberation, but not otherwise. This is also stated by Brahmā in Śrīmad-Bhāgavatam (SB 10.14.4):
- śreyaḥ-srutiṁ bhaktim udasya te vibho
- kliśyanti ye kevala-bodha-labdhaye
- teṣām asau kleśala eva śisyate
- nānyad yathā sthūla-tusāvaghātinām
"My dear Lord, devotional service unto You is the best path for self-realization. If someone gives up that path and engages in the cultivation of knowledge or in speculation, he will simply undergo a troublesome process and will not achieve his desired results. A person who beats an empty husk of wheat cannot get grain, and one who engages simply in speculative knowledge cannot achieve the desired result of self realization. The only gain is trouble."
