True love is not a feeling but a state of consciousness. Those who cultivate true love as a state of consciousness see everything anew, for love has this extraordinary capacity of making us see human beings, nature and the creatures inhabiting it as we were seeing them for the first time.
Only love is able to sense the subtle currents of life that pass through us, and these currents are constantly being renewed.
Objective and physical knowledge of what exists is not enough to fulfil us.
Take for example someone who might be capable of exploring the entire universe: they would end up feeling a void, and even feeling bored if they have not learnt to make contact with the subtle currents of life that flow through all beings and through everything.
