According to Osho, if love is judged as lust, recognize this as a product of repressive, life-negative conditioning. Don't deny or condemn the energy; say a wholehearted yes to life and meet it with awareness. Through watchfulness and acceptance, raw desire is refined into love, intimacy, and prayerfulness, while egoic moralizing, built on nos, dissolves. Come closer to existence, not away from it.
Instead of suppressing, say yes to life and watch your feelings; then what seems like lust can grow into real love.
