The earliest meditation practices appear in the Vedas (c. 1500 BCE). The Upanishads describe profound states of inner absorption called Samadhi. The Buddha, after years of rigorous practice, attained enlightenment under the Bodhi tree in Bodh Gaya — creating a meditation tradition that spread across Asia. The Siddhas of South India developed their own powerfully unique traditions of Kundalini and Nada yoga that survive to this day.

• Vipassana — direct insight into impermanence, suffering and non-self
• Trataka — steady gazing at a candle flame to develop one-pointed focus
• Ajapa Japa — spontaneous, breathless repetition of the mantra So-Ham
• Nada Yoga — merging consciousness with the inner sound (Anahata Nada)
• Yoga Nidra — the yogic sleep: deep relaxation touching delta brainwaves
• Shambhavi Mudra — turning the gaze to the third eye centre
• Transcendental Meditation — mantra-based for effortless deep rest
• Vicharana — self-enquiry in the tradition of Ramana Maharshi

Decades of research confirm that meditation physically reshapes the brain. Regular practice increases grey matter density in the prefrontal cortex (attention, decision-making), thickens the insula (self-awareness), and shrinks the amygdala (fear response). Long-term meditators show gamma brainwave synchrony not seen in non-meditators — a state the Tibetans called "rigpa" and the Vedantins called "Turiya." The ancient maps were accurate.

The tradition speaks of four fruits: Shama (stillness of mind), Dama (mastery of the senses), Uparati (withdrawal from desire), and Titiksha (equanimity in pleasure and pain). Modern science adds measurable improvements in immune function, telomere length, cortisol regulation, and sleep quality. But the deepest fruit, say the masters, cannot be measured — it is the simple, unshakeable recognition of who you already are.
