Nomenclature of the Absolute (pg 35-38)
This love is the only thing to be sought from Krishna and He gives us all sorts of facilities by which we can offer our services to Him in any one of the five different stages. He has assured us firmly that He would accept us if we tend to submit to any one of the five. The only crucial point is that we should offer our services unconditionally so as to give something to our Lord and not to get something from the Lord. We should not have any desire ushering the devotional attempts and should not compel Him to give us something in return. If we have any the least touch of a selfish motive we will surely fail to prove ourselves genuine devotees. We should regulate ourselves in such a manner as to be always serviceable to Him and never desirous of getting from Him any boon or comfort in return. To get service from Him is to claim a part of the Enjoyer Krishna which is the greatest offence in a true devotee. So we should have a devotional temperament to Kamadeva (Madhava) and not the temperament of an enjoyer of this world. This is the true service to Him, which all unalloyed souls can do but which the mind cannot do properly when directed by wrong speculations. In fine I may say that we have many things to supplement these devotional topics by way of elucidating different ideas which are no doubt puzzling. The only thing that we should have is an unalloyed and unconditional devotional spirit which is quite different from the mentality of an elevationist or a salvationist. An unconditional devotional mood is the only function of the unalloyed soul. We should underline this cardinal point many times, and a full understanding of it will bring Prema for us from the Supreme Lord.
There is more than enough food, water, fuel and so on to satisfy the actual needs of everyone on the planet. But there is not enough to satisfy everyone's greed. Even if it were physically possible for you to consume all the food, water, and fuel in the world, you still would not be satisfied. "Material food" cannot satisfy spiritual craving. Since the materialist is never satisfied, he never feels that he has had enough.
If you are not engaged in the service of Hari, you will be either a jnaani (follower of absolute monism), or a karmi (performer of scriptural rites for securing pleasures in this life or the next), or an unabashed servant of worldly desires without restraint.
Therefore, it is necessary that you should call on Him, loudly uttering the mahaamantra [sic] (Hare Krishna, Hare Krishna etc). When you loudly recite Shri Krishna's Names, keeping count of the number of times they are uttered, all the evils are steadily got over; and lethargy vanishes with all its concomitant defects; and even people of an antagonistic nature, apathetic to Hari, will be forced to give up their mockery. "Those who come to scoff will remain to pray" with you.
