So in order to enjoy this spiritual pleasure, you have to practice some tapasya, austerity. Because you are spiritual, every one of us, spiritual, ahaṁ brahmāsmi. We are not this material body. We change. It is for certain years. Again we change: another body, another body. This changing of body is going on because we are seeking material pleasure. So God is giving us different types of body for enjoying different types of material pleasures. But if you want to enjoy spiritual pleasure, then you do not require to change body. That is the mission of Kṛṣṇa consciousness. That every one of you want pleasure, but that pleasure, in the material world, you cannot enjoy perpetually. But if you purify yourself of this material contamination, if you do not accept this material body again, and you remain in your spiritual body, then you enjoy transcendental bliss eternally.
So this human form of life is meant for that purpose. Lower than the human form of life, cats and dogs, they cannot understand what is spiritual pleasure. That is not possible. But in the human form of life you can understand what is spirit and what is matter and what is spiritual pleasure and what is material pleasure. This distinction we can make. That much consciousness is developed in the human form of life
