I wonder whether unmasking superficial desires as disguises for deep-seated psychological issues has ever worked for anyone in practice. So ok, craving that new shiny car is allegedly just a symptom of a lack of self-esteem. Does such an insight really help? And wouldn't that new shiny car go
in fact a long way towards boosting your self-confidence? Unless you're a hermit or a monk, you have to navigate the stormy seas of desire somehow, for most of us it's a task that can't be avoided.
I'm currently reading various books on yoga and Buddhism, and of course they all stress the ideal of being frugal and free from desire, with lots of examples where the fulfillment of desires (also in romantic relationships!) only leads to more frustration and misery. I have to say I don't entirely buy it. Being frugal and free from strong desires may grant you more autonomy in your decisions but only when you've genuinely arrived at a point in your spiritual development where such cravings have disappeared by themselves; the average reader, however, will only repress his or her desires and play pretend in order to conform with those ideas, with predictable results.
Another strategy which some advocate is dissociation. It's popular with spiritual seekers who've already developed some self-awareness and consequently are able to take stock of their drives and urges. It can be a useful ability to have but it can also become a trap. It has frequently been an infuriating experience for me personally whenever I discovered what's truly going on inside me while being utterly helpless to do anything about it, and that's why I don't such a great store by mere insights anymore - "Cool realisation, dude, but is it actionable?" It's the
illusion of control that's so enticing and treacherous. You can employ your sweet reason to disentangle the motives behind your desires but influencing or even transforming them is quite another matter.
There's this NewAge platitude "I have emotions but I am not my emotions." Yes, you are. A huge part of your personality is defined by your likes and dislikes, and claiming that deep down, you're this wise, calm and enlightened person simply means lying to yourself - dissociation at work yet again.
The Buddhist approach to dealing with desire varies according to school - frequently the analogy of the poisonous plant is used:
Theravada: avoid the poisonous plant or cut it off.
Mahayana: confront it and root it out to prevent it from growing back, find an appropriate antidote.
(Tantric) Vajrayana: devour the plant and transmute its poison into enlightenment energy.
The Tantric approach is frequently quoted but it's a very advanced practice in Tibetan Buddhism, and monks are required to work through the previous two stages as part of their training first. Basically it's Freudian sublimation, and I'm not very confident it can work as a deliberate intervention, Freud's idea looks more like an involuntary coping strategy to me. I must say I don't trust modern psychology in this respect anymore, Hinduism and Buddhism go deeper and pay more attention to the subleties involved, in my opinion.
