The Apollonian may have a defective Heart line, but it will not be found entirely absent with him; neither will it be with the Venusian, as these two types have too much sympathy and feeling ever to be absolutely deficient in heart. The Lunarian may be found with the line absent, or badly deficient, as he is naturally cold and selfish. Fortunately, you are not likely to meet many Lunarians. So the absent line of Heart will tell you that the subject lacks heart in a moral way, is cold and selfish, and that he will also be cowardly and sneaking in his disposition, though sometimes a great "bluffer." The line of Heart generally rises from some point on or near the Mount of Jupiter, sometimes extending over and rising on the Mount of Saturn. Sometimes the line has forks at its beginning, all of which may start from Jupiter, and sometimes these forks spread like a fan, extending over as far as Saturn.

There are three well-verified readings attached to three starting points, and these should be used as a basis for your work, modifying and changing them in accordance as you see the starting points vary. 1. Rising from Mount of Jupiter (25) we read the development of the sentimental side to the affections. The subject is one whose love is ideal, to whom love is an adoration, and to whom love, even with poverty attached, is attractive. 2. Rising between Jupiter and Saturn (26) the line shows the common-sense, practical, "middle ground" with the affections, indicating one who is not carried away with sentiment, but who views love from a practical standpoint; is not "soft" or "spoony," but who is inclined to think that love in a cottage without plenty of bread and butter is a myth. This person is never carried away by sentiment, and while strong in affection is sensible and not foolish. 3. Rising from the Mount of Saturn (27) the marking shows the sensualism in the affections of one whose love is tinged with the idea of pleasures from sexual relations. This is infallible if with it is seen a large Mount of Venus of pink or red color, and with strong Life and Mercury lines.
These will tell of physical desire by the point at which the Heart line starts, and of physical strength sufficient to carry out these desires by the other indications.

Where the Heart line rises from all three of these sources (28) we have indicated the union of sentiment, common-sense, and passion, showing that heart is the strongest factor in the make-up of your subject, and a very fine Head line and a strong thumb must be present to prevent heart from ruling head. With this strong formation you can, by noting which of the three lines is the deepest at the starting point, tell whether sentiment, common-sense, or passion is the strongest force. This always produces an affectionate person, who has a warm heart, a great deal of it, and loves friend, relation, and mankind in general. His danger is too much heart, and he does not always look after his own interests when considering those of others. This will be increased if the fork from Jupiter is strongest, and decreased if the middle branch is strongest, because the practical side will then be prominent. The fork of the Heart line will not always be so pronounced as that shown in the illustration, but every variation of it can be read based upon the full indication here given. Sometimes the line will start in several forks on Jupiter alone, in which case it increases the sentimentality of a single line starting from that point. The same rule applies to the other starting points.
The general rule applies that a single line tends to make the affections more self-contained, and the subject loves family and friends strongly, but does not reach out to everybody as does the one whose Heart line forks at the start. The deeper and clearer the line at the start, the deeper, but more likely to be selfish, are the affections. The more the branching, the more they go out to many people. The line beginning with a fork makes a successful subject, for he has many friends. Sometimes the line of Heart inclines to fall toward the line of Head at its start (29). This shows the head to be powerfully in the lead, and that when it comes to a choice between sentiment and utility the heart will be second best. Sometimes the line starts from the line of Head (30), in which case it will show that head has control of heart and completely dominates it. This is especially true if the Head line be deeper and clearer than the Heart line. If it is so marked, read with confidence that the head completely rules. If the lines of Head and Heart are marked as in the above two cases, there will be a continual struggle between them for supremacy, with the chances in favor of the head as the Heart line droops or takes its source from it.
The constant effort in our study of the hand is to discover what forces are strongest in the subject, and what ones will most influence him. In this battle between head and heart, reason and sentiment, minutely inspect the source of the Heart line and with it the comparative strength of the two lines, Head and Heart, in order to tell which will rule. Note in practice that the Heart line when rising from the Head line does not always do so just at the start, as in the illustration, but may rise farther along in the course of the Head line (31). In this case the time at which the Head line obtained control of the Heart line can be read by the point on the Head line from which the Heart line starts; the age at which it occurred being read from the line of Head according to the rules laid down in Chapter IV (The Age Of The Subject - Age As Indicated On The Lines).

In the above examinations you will be much assisted by having first classified your subject into his proper type. The Saturnian will be most apt to be ruled by head, followed by the Lunarian, the Mercurian, the Jupiterian, and the Martian, named in the order as this tendency is found. The Apollonian and Venusian incline to have heart lead them. With the above markings base the strength of your statements of the indications upon the type as well as the indications of the line itself, and you will arrive at absolute accuracy. The length of the line should next be noted, for it will tell of much or little heart. If the line rises normally but runs only a short distance and stops (32), it indicates that the subject will have serious difficulty at the time at which it ends, even if all the other lines go on to their normal length. This abrupt termination of the Heart line means either that the heart will stop beating, or else that the subject has little heart or affection for others. You can judge which by the directions given later in this chapter. It is, in either case, a poor sign. If the Heart line crosses the entire hand (33) it shows that the subject has too much heart and will allow sentiment to guide him in everything.
