At present only a small portion of the knowledge contained in the Vedas, Vedānta-sūtra, and Upaniṣads is available to the general populace. What is noteworthy, however, is that the essence of all Vedic knowledge is available in the Gītopaniṣad, popularly known as the Bhagavad-gītā. Lord Kṛṣṇa milked the cow of the Upaniṣads, and Arjuna drank the milk thus obtained - the Bhagavad-gītā. If Arjuna found time to hear the Bhagavad-gītā in the middle of a battlefield at Kuruksetra, then what urgent business is stopping us from hearing the Gītā? When knowledge of the Gītā spreads, then everyone will easily be able to attain the platform of yoga. And as the pure devotees of the Lord become successful in their efforts to use their spiritual intelligence in the Lord's service, then the science of love of God taught by Lord Caitanya, the most magnanimous incarnation of Godhead, will be distributed everywhere. Judging from all the symptoms, the time is now ripe. Indians should now take shelter of their saintly preceptors, the pure devotees, and unitedly propagate the glorification of Kṛṣṇa via the medium of the Bhagavad-gītā. In this way the world will become prosperous and perfect. The present age has seen interest in spiritual matters markedly increase. Yoga and meditation societies have mushroomed expressly to transmit the knowledge of the Bhagavad-gītā, but how this will be accomplished is still a question. We are confident that Lord Caitanya's teachings on the process of loving devotional service will easily harmonize all conflicting concepts.
The most effective method for directing humanity toward a positive and favorable consciousness is available in India. Any person, under any circumstances, can reach an elevated state of consciousness by properly hearing the Bhagavad-gītā, and then, by constantly chanting the name of God, he can win God over. The present state of world affairs is full of foreboding, strife, and struggle. These are the effects of Kali-yuga. But our faith in the eternal nature of jīva prompts us to believe that anyone can attain devotional service to Kṛṣṇa simply by hearing and chanting His name and thereby awakening his inherent dormant love for Him. We have full faith in the words of Śrīla Śukadeva Gosvāmī quoted above from the Śrīmad-Bhāgavatam - that simply by chanting the name of Kṛṣṇa one can reach His eternal kingdom.
Therefore all signs point toward auspicious changes in the global consciousness. But these changes must be initiated from within every individual's heart; they are impossible to accomplish through political lobbying or social adjustments. The devotional feelings that reach out from within the hearts of men find their culmination in the pure devotees' spiritual perfection. In the Bhagavad-gītā Lord Kṛṣṇa describes this spiritual perfection as bhakti-yoga, or buddhi-yoga, the yoga of devotional service. At a certain stage, all the systems of yoga become obsolete and have to be discarded - except for buddhi-yoga.
