actually unless one is saved by the supreme authority, there is no question of saving him by so many philanthropic work. Actual saving is this Kṛṣṇa consciousness movement. Because if one is raised to his Kṛṣṇa consciousness, the whole problems of his life will be solved. That is real welfare activity. Other things you cannot change. If one is destined to suffer by some agency, you cannot stop. Therefore Bhāgavata says, tasyaiva hetoḥ prayateta kovido na labhyate yad bhramatām upary adhaḥ (SB 1.5.18). You simply try to awaken your Kṛṣṇa consciousness, which was impossible in other living conditions. Either going to the heaven planet or going to the hell planet or becoming Brahmā or ant... Do not try for all these elevations. Simply try for awakening your Kṛṣṇa consciousness.
Then why so many people are trying for happiness? The answer is: tal labhyate duḥkhavad anyataḥ sukhaṁ kālena sarvatra gabhīra-raṁhasā. Nobody tries for distress, but distress comes; similarly, even if you do not try for your happiness, if you are destined, happiness will come. But if you take to Kṛṣṇa consciousness, it is simply happiness. There is no more distress. If we become steadily situated in Kṛṣṇa consciousness, then it is simply happiness. As Prabodhānanda Sarasvatī has explained, viśvaṁ pūrṇaṁ sukhāyate. There is no problem for a devotee. Viśvaṁ pūrṇam... Everyone is perplexed with the problems of this universe, but for a devotee, viśvaṁ pūrṇaṁ sukhāyate.
