Just translated this from Ahad ha-Am
on the concept of 'Love of Israel'.
In truth, great is the power of confidence when it flows from an internal source, from the source of the heart’s yearning to achieve its goal – where the confident man is clear about the way ahead and the obstacles which lie along his path. This yearning gives him the strength to believe in himself and envisage the victory which will be his over impossible obstacles. However, this will not happen if his confidence is mere waywardness, arising from lack of knowledge - if the motivating factor is not the heart’s yearning, but rather the false view that this or that way is fraught with danger and that he will easily achieve his desires. In this situation, confidence will prove to be not the power that surmounts all obstacles, but rather, on the contrary, a negative force, a new obstacle to be added to all those other external obstacles. As soon as this man encounters an opposing force and realizes his error, he will retreat in fear and bitterness and – not being at all prepared for war, - is in imminent danger of falling victim to absolute despair.
Reminds me of part of the Hindu Bhagavad Gita
