- "From a still wider and more comprehensive point of view, universal life itself appears to us as a struggle between multiplicity and unity - a labor and an aspiration towards union. We seem to sense that - whether we conceive it as a divine Being or as a cosmic energy - the Spirit working upon and within all creation is shaping it into order, harmony, and beauty, uniting all beings (some willing but the majority as yet blind and rebellious) with each other through links of love, achieving - slowly and silently, but powerfully and irresistibly - the Supreme Synthesis."
- Roberto Assagioli, Psychosynthesis, 1976, p. 31.
- "Only the development of his inner powers can offset the dangers inherent in man's losing control of the tremendous natural forces at his disposal and becoming the victim of his own achievements."
- Roberto Assagioli, The Act of Will, 2002, p. 6
- "Psychosynthesis brings the matter to a point of extreme simplicity, seeing the self as the most elementary and distinctive part of our beings - in other words, its core. This core is of an entirely different nature from all the elements (physical sensations, feelings, thoughts and so on) that make up our personality. As a consequence, it can act as a unifying center, directing those element and bring them into the unity of an organic wholeness."
- Piero Ferrucci, What We May Be, 1982, p. 16
- "The factors that contributed to my growth were many - finding someone who understood me, exploring the unconscious, awakening my latent love . . . but one star is brightest among all: the self. I found the source of livingness inside me, something I didn't even know existed."
- Piero Ferrucci, What We May Be, 1982, p. 16
- "The quality of the helping relationship, based on unconditional love and close attunement to the client, is the indispensable context without which techniques are mere mechanical gimmicks which will lack true healing power. The level of the guide's personal integration is a crucial element which determines the amount of clarity and love he/she is able to bring to the traveler on the Path."
- Marsha Crampton, Psychosynthesis: Some Key Aspects of Theory and Practice, 1977, p. 50
- "Almost any method can be useful in the process of Psychosynthesis if it is consciously chosen by the guide and client, and is in harmony with what is already occurring naturally. Rather than being 'eclectic' in methodology, a term which implies a grab-bag approach, the guide can seek to synthesize the various methods with guidance from the Higher Self of both guide and client."
- Molly Young Brown, The Unfolding Self, 2000, p. 64
