Tantra sadhana (practice) reweaves the fabric of life and restores it to its original pattern. No other path of yoga is as systematic or as comprehensive. The profound practices of hatha yoga, pranayama, mudras, rituals, kundalini yoga, nada yoga, mantra, yantra, mandala, visualization of deities, alchemy, ayurveda, astrology, and hundreds of esoteric techniques for engendering worldly and spiritual prosperity blend perfectly within the tantric disciplines.
Tantric masters discovered long ago that success in both the outer world and the spiritual realm is possible only if we awaken our latent power, because any meaningful accomplishment, and especially the attainment of the ultimate spiritual goal, requires great strength and stamina. The key to success is shakti - the power of soul, the power of the divine force within. Everyone possesses an infinite (and indomitable) shakti, but for the most part it remains dormant. And those whose shakti is largely unawakened have neither the capacity to be successful in the world nor the capacity to enjoy worldly pleasures. Without access to our shakti, true spiritual illumination is not possible. Awakening and using shakti is the goal of tantra, and this is why tantra sadhana is also known as shakti sadhana.
