Human Personality, Destiny and Ethics
The Five Aggregates (Khandas)
Buddhism rejects the idea of a fixed, permanent soul. Instead, what we call a ‘person’ is a constantly changing combination of five factors called the five khandas (Sanskrit: skandhas) or five aggregates. These are:
- Form (rupa): the physical body and material world, including the five senses and their objects.
- Feeling (vedana): the pleasant, unpleasant or neutral quality of each experience.
- Perception (sanna): the ability to recognise and identify objects and experiences.
- Mental formations (sankhara): volition, intention, habits and mental tendencies—including the kamma-generating actions of mind.
- Consciousness (vinnana): awareness itself—the knowing quality that registers sense data and mental events.
None of these five aggregates constitutes a permanent self. They are all subject to the Three Marks of Existence: they are impermanent (anicca), they contribute to suffering (dukkha), and none of them alone or together constitutes a fixed self (anatta). The five khandas are interdependent, arising through dependent origination. Theravada Buddhism uses the analysis of the khandas to demonstrate anatta empirically: look carefully at any aspect of what you call ‘yourself’ and you will find only these five shifting, conditioned processes—never a permanent ‘I’.
The five khandas are: form (rupa), feeling (vedana), perception (sanna), mental formations (sankhara) and consciousness (vinnana). Theravada Buddhism uses the khandas to support the doctrine of anatta (no fixed self): because each aggregate is impermanent and conditioned, none of them—alone or together—can be a permanent, independent self.
Mahayana Buddhism extends the Theravada analysis in important ways. The Heart Sutta (Prajnaparamita Hrdaya Sutra) famously declares that ‘form is emptiness, emptiness is form’—a statement of sunyata (emptiness). Sunyata extends anatta beyond the self: not just the person but all phenomena lack inherent, independent existence. Everything exists only through dependent origination.
The Diamond Sutta (Vajracchedika) teaches that no fixed marks or characteristics belong to any phenomenon. Both the Heart and Diamond Suttas use paradox and negation to point beyond conceptual thinking toward direct insight. Alongside sunyata, Mahayana tradition also teaches tathagatagarbha (buddha-nature)—the idea that all sentient beings already have the seed or potential for Buddhahood within them. This teaching stands in creative tension with sunyata: everything may be empty of fixed nature, yet there is a positive capacity for Enlightenment in all beings. Pure Land Buddhism connects tathagatagarbha to the story of Amida Buddha, who vowed to enable all beings to be reborn in the Pure Land as a step toward Buddhahood.
Arahant and Bodhisattva
The ideal of the liberated person differs significantly between Theravada and Mahayana Buddhism. In Theravada, the highest goal is to become an Arahant (Sanskrit: Arhat)—a person who has completely eliminated the three poisons and all craving. An Arahant has walked the full Eightfold Path and at death attains Parinibbana: complete liberation with no further rebirth. The Arahant exemplifies personal liberation through discipline and meditation. In Mahayana, by contrast, the highest ideal is the Bodhisattva—a being who has vowed to attain full Buddhahood for the benefit of all sentient beings.
Santideva’s Bodhicaryavatara (3:6–20) expresses the Bodhisattva aspiration powerfully, vowing to remain in the cycle of existence, taking on the suffering of others, until all beings are liberated. The Bodhisattva deliberately delays their own final liberation, motivated by karuna (compassion) and metta (loving kindness). Pure Land Buddhism speaks of Pure Land as a realm created by Amida Buddha’s compassionate vow, accessible to those who call on his name with sincere faith, and providing ideal conditions for achieving Nibbana.
Kamma, Rebirth and the Middle Way
Kamma (Sanskrit: Karma) is the law of intentional action and its consequences. Every deliberate thought, word and deed plants a seed that will bear fruit in this or a future life. It is important to note that Buddhist kamma is about intention, not just outcome: it is the intention behind an action that determines its kamma-generating quality. Unskilful actions (rooted in Lobha, Dosa or Moha) generate negative kamma; skilful actions generate positive kamma. The result of kamma over many lifetimes is punabbhava (rebirth or rebecoming)—the continuation of the cycle of samsara.
The Five Precepts (pancha sila) are the ethical foundation of lay Buddhist life. They are: (1) to abstain from taking life, (2) to abstain from taking what is not given, (3) to abstain from sexual misconduct, (4) to abstain from false speech, and (5) to abstain from intoxicants. The Karaniya Metta Sutta teaches the practice of universal loving kindness (metta) toward all beings without exception.
Buddhist ethics are grounded in the concept of internalisation of virtue: the goal is not merely outward compliance with rules but the cultivation of inner states—compassion (karuna), loving kindness (metta), equanimity (upekkha) and sympathetic joy (mudita)—that naturally express themselves in skilful action. The Five Precepts (pancha sila) express sila (ethical conduct) in practical form for lay people.
Buddhist ethics use the language of ‘skilful’ (kusala) and ‘unskilful’ (akusala) rather than ‘good’ and ‘evil’. This framing reflects the tradition’s emphasis on intention and consequence: an action is skilful if it is rooted in non-attachment, kindness and wisdom, and unskilful if it arises from the three poisons (Lobha, Dosa, Moha). Skilful actions reduce suffering and generate positive kamma; unskilful actions increase suffering and generate negative kamma.
The Middle Way is not just a guideline for the physical lifestyle of practitioners (avoiding extreme asceticism and indulgence); it also applies to moral conduct. Santideva’s Bodhicaryavatara (3:6–20) presents the Bodhisattva’s ethical ideal as balancing compassion for others with the wisdom to act effectively. Karuna and panna must work together: compassion without wisdom may cause harm; wisdom without compassion becomes cold. The Six Perfections (paramitas)—generosity, ethics, patience, energy, meditation and wisdom—express this balance. These are the Mahayana elaboration of the ethical dimension of the Buddhist path, cultivated over many lives by the Bodhisattva on the way to full Buddhahood.
