According to Osho, samadhi flowers naturally when understanding ripens into choiceless awareness: a smokeless, assumption-free consciousness in which thought falls silent and 'what is' is seen as it is. This is not intellectual cleverness but wakefulness. Nurture it by doing everything with awareness or by daily meditation; even an hour of silent seeing spreads through the day, resolving mind’s turmoil into mirror-like clarity—samadhi.
When you watch everything without thinking or guessing, your mind becomes a clean, quiet mirror—and that clear seeing is samadhi; practice it in daily actions or by sitting quietly each day.
