Now does the Kalama Sutta suggest, as is often held, that a follower of the Buddhist path can dispense with all faith and doctrine, that he should make his own personal experience the criterion for judging the Buddha's utterances and for rejecting what cannot be squared with it? It is true the Buddha does not ask the Kalamas to accept anything he says out of confidence in himself, but let us note one important point: the Kalamas, at the start of the discourse, were not the Buddha's disciples. They approached him merely as a counselor who might help dispel their doubts, but they did not come to him as the Tathagata, the Truth-finder, who might show them the way to spiritual progress and to final liberation.
Thus the discourse to the Kalamas offers an acid test for gaining confidence in the Dhamma as a viable doctrine of deliverance. We begin with an immediately verifiable teaching whose validity can be attested by anyone with the moral integrity to follow it through to its conclusions, namely, that the defilements cause harm and suffering both personal and social, that their removal brings peace and happiness, and that the practices taught by the Buddha are effective means for achieving their removal. By putting this teaching to a personal test, with only a provisional trust in the Buddha as one's collateral, one eventually arrives at a firmer, experientially grounded confidence in the liberating and purifying power of the Dhamma. This increased confidence in the teaching brings along a deepened faith in the Buddha as teacher, and thus disposes one to accept on trust those principles he enunciates that are relevant to the quest for awakening, even when they lie beyond one's own capacity for verification. This, in fact, marks the acquisition of right view, in its preliminary role as the forerunner of the entire Noble Eightfold Path.
Partly in reaction to dogmatic religion, partly in subservience to the reigning paradigm of objective scientific knowledge, it has become fashionable to hold, by appeal to the Kalama Sutta, that the Buddha's teaching dispenses with faith and formulated doctrine and asks us to accept only what we can personally verify. This interpretation of the sutta, however, forgets that the advice the Buddha gave the Kalamas was contingent upon the understanding that they were not yet prepared to place faith in him and his doctrine; it also forgets that the sutta omits, for that very reason, all mention of right view and of the entire perspective that opens up when right view is acquired. It offers instead the most reasonable counsel on wholesome living possible when the issue of ultimate beliefs has been put into brackets.

But I see it this way. People can either belief that:
1) There is no rebirth:
----- You practice the Dhamma to be free from suffering in this life.
Yes, they can. But no need to be a monk, hold celibacy, practise deep meditation and numerous precepts on the highest and sublime level and ect. No need to make dana to monks also. That is why Buddha said that in this case "There is no holy life".
