The human body is rarely achieved and although temporary like other bodies, it is meaningful because in human life one can perform devotional service. Even a slight amount of sincere devotional service can give one complete perfection.
Philosophical research culminates in understanding the Supreme Personality of Godhead. After achieving this understanding, when one becomes free from the material modes of nature he attains the stage of devotional service. Either by devotional service directly or by philosophical research, one has to find the same destination, which is the Supreme Personality of Godhead.
In the preliminary phase of spiritual life there are different kinds of austerities, penances and similar processes for attaining self-realization. However, even if an executor of these processes is without any material desire, he still cannot achieve devotional service and aspiring by oneself alone to achieve devotional service is also not very hopeful, because Krishna does not agree to award devotional service to merely anyone. Krishna can easily offer a person material happiness or even liberation, but He does not agree very easily to award a person engagement in His devotional service. Devotional service can in fact be attained only through the mercy of a pure devotee.
Devotional service is dependent on the mercy of Krishna and His devotees. Unless we surrender to the lotus feet of a pure devotee, it is not possible to come to the platform of pure devotional service. By his own efforts a bee cannot taste the honey within a bottle. The bottle must be opened by a superior. If the bee simply licks the outside of the bottle, thinking “Now I am tasting honey,” then he is in illusion. Similarly, no one can enter into devotional service unless the door is opened by a devotee.
From association with devotees is born faith. From faith is born pure knowledge. From pure knowledge is born meditation. From meditation is born devotional service, which pleases Lord Krishna and destroys all sufferings.
One should not be impatient in discharging devotional service, but should take instructions from the spiritual master and execute them with patience, depending on the mercy of guru and Krishna. The successful execution of Krishna conscious activities requires both patience and confidence.
